The Friday morning CX electrical report from Monsieur Dubois is not very good.
Engine bay wiring in generally poor state to the point of being a fire risk in places, "mostly bodged", so he will install a parallel circuit for now to ensure that the alternator gets its signal and will charge the battery so that the battery warning light goes out as it is supposed to.
To try to return the wiring to anything like standard (he's had 3 CXs himself and claims to know them inside out) will take at least one full day and cost a minimum of £700. I think we'll leave that job for later in the year or in the New Year. I just need the car to work for now so I can take it to shows and run it to the stables at weekends without the spectre of a flat battery ever hanging over me.
The camshaft pulley also needs attention as it appears distorted so he'll do that.
'tis not all bad news. He took it for a spin and says he was impressed by how strong the car felt (not surprising as it has barely covered 80,000 miles in 30-plus years) and he confirmed that the body, floorpan, etc. requires nothing at the moment (probably because it spent most of the eight years up to October 2017 sitting in a garage or a shed).
Somewhere along the line I'll have to spend the money to have the electrics properly restored. Just not now.
