RichardKs wanderings: IMA fix an Insight. At least, seem to have done so...

[RichardK]

This year has just been truly shitty in many ways, and I definitely didn't expect to have a birthday at this age, in this situation. But it could be worse, both materially, and indeed, existentially, as I may not have had a birthday at all.

Keeping it on-topic, a quick car rundown:

In order of shiteness...

The Focus CC keeps being a Focus, the tyres are now so bad I won't drive it - and I just had to renew the insurance, which Aviva put up to £350 but that's okay because I did the usual TopCashBack + Comparison site and got a quote of £228, with £45 cashback. That'll do. The Android head unit keeps working, the reversing camera in the boot release handle is the best thing ever, and the interior is mostly dry (but the boot does get damp, I think because I need to renew some seals after removing the chrome trim). The alternator may be on the way out as the lights dim appreciably when the engine changes speed during parking.

It has one new genuine Ford headlight which has shitty beam alignment (the lenses are one lens, so it's the bulb mounting) and is part chrome and part black. Not impressed with Ford for that one.

MOT is up in March I think. I also suspect that if I sort the tyres it might pass. Tempted to put C6 WOE plate on it, as that would be cheaper than replacing the plates (since I already have plates).

The Honda HR-V MOT is up in January. It still makes a rumble noise from the engine moving and exhaust hitting the subframe if you pull away with anything other than the gentlest of throttles, but otherwise seems to be doing well. When it's warmed up and idling it's almost inaudibly quiet, a quality we used to be proud of achieving with a petrol car. It has been waxoyled so I'm hoping the winter won't kill it, because it's just lovely, if a little too small a lot of the time. Seriously considering getting a five-door one.

The Porsche is lurking. I still need new tyres, to align the roof properly, and probably a set of coffin arms I'd tried to be organised and buy from this very parish then just... had too much shit to deal with.

(The shit has reached the stage where I sold my perfect, boxed, Apple //e system and have put my Apple IIgs on eBay, admittedly for an eye-watering amount because it would help. I do have some work incoming, and honestly, I think that's about the main reason I get to have a birthday).

The RX-7 has not progressed, because of the small bit of rust I found. I am just torn on how to tackle it, whether I treat it and consider it reasonable, or have it fixed sine the car needs a proper restoration, or what. My common-sense brain says "make the car run first, then see" but my rational restoration brain says "bodywork is everything on an RX-7, the engine is meccano that people rebuild every three years if they drive it seriously".

The Sinclair C5 has a damaged-but-acceptable headlight, some Land Rover/Metro front indicators, a new front brake cable partially fitted, and a set of stickers. I need rear wheel centre caps then it'll be visually acceptable, but my long term thoughts are a cut-down scooter or similar axle with motor and differential to give it proper rear-wheel drive rather than 'inside wheel and no suspension' which means on a left-hand bend the wheel can lift and lose traction.

You'll think that'd be me sorted for the rest of the year, but something's showing up today to occupy my brain a bit...

The serious thought is "if I need to cut costs before spring and proper Boxster selling weather, should the HR-V or the Focus go"? I really can't decide at all.

Why do things with too many wheels make me think of Gerry Anderson or other bad scifi?

[RichardK]

Maybe it's not the wheels bringing back the sci-fi vibe

Welcome to 1999 Honda Dealer OF THE FUTURE

Apparently this insight wants to be a regular car. I intend to make it hybrid again.

Hmmm, now you mention it.....

 

To be honest I'm just relieved I managed to thread my 20footer through your estate and get it turned around.... It gives me sleepless nights every time I plan a trip that doesn't stick to arterial roads 😅 

Good to see you again today and looking forward to your, er, insight on the Honda!

your estate

Uh not sure about that, but understand you wouldn't want to churn the grass up? 😀

[RichardK]

This morning, @mat777's Honda is showing a full set of lights on the CTek, which is charging the regular 12V battery. It drove off the trailer fine, and didn't need jump starting, but while we were freezing to death and chatting the OBD-II reader was also indicating the Honda would like to die too. The voltage readout suggested the alternator wasn't doing much. Except the Insight doesn't have an alternator.

I've never seen one before, but because I've written a fair bit on these and talked to specialists about HEVs generally, I made two assumptions. One, that the 12V battery was inevitably going to me more important than makes sense for a car that is a massive battery on wheels, and two, it doesn't use an alternator because it doesn't have a belt-driven reversible starter, though I thought the principle would be similar to 48V mild hybrid setups. Part of my brain could picture a cutaway engine package for an Insight with a motor sandwiched where you'd expect a flywheel and clutch, and that's pretty much right.

My gut feeling is that somehow, the DC-DC charging system for the 12V battery had shit itself and has subsequently drained the IMA battery, but because the car uses the high voltage battery to start, the usual tell-tale "RER RER RER" of a dead battery wasn't going to happen. Plus with a huge motor and at least 10x the typical alternator output of 14.4V lurking in the big pack feeding it, a fairly dead traction battery will wake that bunny up again.

So, power on. No alternator warning light, which is predictable, and the start up display did a flash of 'battery charge' lights. But still has the IMA light. Now, the IMA battery is really depleted, down to one line. In this cold and miserable foggy day, the Insight has been rudely awakened with 155V up the backside (now 174V. As I understand it, it should reach 176V then fall to 167V float when charging is complete). I'm going to leave it sitting on the main battery charger until fully charged, and see how it looks with a charged up main pack and a charged 12V battery, though I suspect there's still something to be addressed in the DC-DC converter.

That could be as simple as one of the big fuses.

Even as a Citroen fanatic and someone who likes JDM cars, the Insight hurts my brain to look at one close up. It's so WIERD. I kinda like it, it's a shame it's out of my budget. The tapered shape and two-seat layout is so purposeful, yet (a bit like the HR-V's small body, real 4x4, all the groubd clearance) you can see how this is the stage of "this is the purpose, the intent" and then what we got - FWD tall, overweight, bulky 'small car' or 'The Honda Jazz Hybrid' (we'll gloss over those weird Insight MkIIs, but I am more tempted than ever by the idea of a CR-Z) without any of the super-clever weight saving and obvious aerodynamics.

[RichardK]

So, we have charge in the big battery, and we have charge in the small battery:

But we still have an IMA fault, which isn't a surprise yet as all I've done is charge some batteries and remove a fuse to reset a level meter.

What is telling is that with the engine running at idle while reading OBD codes, the voltage is 13.9V with lights on. 14V otherwise. Consistently. So... DC/DC conversion is working and the car probably got sulky when the main pack drained too much to replenish the little one.

Switch the engine off but ignition on, and the standard battery is on 11.9V before you've noticed, so I do think it could be healthier.

Have read up @jonny69's threads on RetroRides to learn a bit about the battery pack and the off-grid boxes - it is a few months since it played up, so I do wonder if it's due a discharge/charge cycle anyway.

Cosmetic stuff at this time of year and in this weather is always miserable but I couldn't resist checking if one of the products I had to hand would be useful...

Spot the difference?

[RichardK]

Spot the difference, part 2:

That is running. No errors. I still need to figure out why it got an error, which means tap testing the cells to be sure, but I suspect a low 12V battery made the car unhappy in a way it didn't expect.

Now to reset the clutch...
