Skizzer’s Elite: Lotushite

When Dermist’s mate Escort Greg came round for GammaAid last week (see http://autoshite.com/topic/27925-gamma-coupe-fix-up-mini-meet-progress/?p=1583641)he also had a look at the Elite, which you may recall had suffered Total Electrical Death again after a recent runaround.

 

I’d been studiously checking connections starting at the battery in the boot. Greg is an expert in elecricity and swiftly found this:

which is the BFO earthing strap that runs along the chassis from boot to engine block, and which had blown out of its terminal connector. The terminal looks like this:

It’s a 10mm diameter cable with an 8mm hole for an attaching bolt, which shouldn’t be hard to source. It needs proper crimping rather than a dab of solder (rolls eyes at previous bodger).

Double school of thought.

 

Crimp cold-welds the copper strands together and to the crimped fitting. Solder likes to work harden and crack with repeated vibration and heat cycling.

 

Chapman would give you squinty eyes, adding such a heavy metal as lead to a vehicle. Adding it! The nerve!

What PhilA said...

I'm sure that for automotive use it should be crimped. The caveat is that you need the correct crimping tool, which is big enough to apply the right amount of pressure.

ETA, something like this...

Agreed, I’m on it with the hydraulic crimper. Greg has one for 2,000 amp cables, but it won’t fit under the Lotus’s bonnet. Or possibly into the shed.

In the last episode’s cliffhanger, our hero was thwarted in his attempt to escape in a shonky Lotus by the main earth cable falling out of its terminal connector...

 

Luckily, just in the nick of time, this arrived from China:

A 16 ton (tonne? Who cares) hydraulic crimping tool. That’ll squeeze some sense into it.

 

Bought a bottle of Coke from the garage to clean up the terminal a bit. Turns out to be cherry flavour- identified only by some tiny writing, WTF?

If I’d been planning on drinking it I’d have been very upset. Does it still have magical cleaning solvent powers?

 

Yes. Ok the connector isn’t super-shiny, but it was only in the evil brew for 20 minutes and the contact surfaces are clean. I trimmed the cable back with my best motorbike-thief spec bolt cutters and pared back the insulation, then persuaded the cable into the terminal:

The crimper has a swivelly head so it was reasonably easy to get it clamped around the terminal.

There was a bit of head-scratching before I worked out that the on-off label is on backwards, then it pumped up nicely and gave the copper a 16 ton(ne) hug. Release and withdraw the crimper...

 

 

...and the terminal falls straight back off again. BOLLOCKS.

It does, from teeny to London Underground spec (nearly), and the 70mm sq block I used should have been about right for about 9mm diameter. With hindsight 50mm sq would have been better - but now the terminal doesn’t want to go back on the cable to re-try it.

 

I ran out of time - I’ve been working all weekend until today and then I had to get back for family stuff. I will try and source some connectors (can’t be that hard) and have another go next time.

I was gonna say you might have used the wrong one. I've bought those connectors before but I can't think were from.

With me, SFU* error is normally a pretty safe bet.

 

Tips for connector sourcing welcomed, especially mixed boxes including 70mm sq flavour so I don't have to buy 1,000 of the fuckers off AliExpress.

Slightly off piste, but I have a childhood memory of Roy of the Rovers driving an Eclat/Elite. Tried to verify it, but I've not found any evidence. Did I just make it up?

Google agrees with your memory - if you put "Roy of the Rovers" in as an image search, an image of "soccer star in car smash" and a rolling Lotus is revealed some way down the page of images. I'd post it here but I am at "work" and this PC won't allow image posting. I'll add it later.

You’re quite right...allow me:

Looks like an Eclat rather than an Elite, with a rare twin headlamp conversion. Note that the headlamps are popped up but not lit, suggesting a problem with either the vacuum or the electrics - neither of which would be any surprise. Could easily be both, of course.

Similar to the code I have seen used several times in the past: PEBKAC "Problem Exists Between Keyboard And Chair"

 

ID10T or layer 8 error.
