Now the engine has been running fine, I have removed the front wiring loom and am in the process of making a replacement. The main reason for this is due to the dodgy wiring that has been evolved over the years. Babs was originally fitted with an alternator with remote control box, and since this has been replaced, there is a lot of DIY wiring around it. Also, the indicators didn't work properly, the temp gauge reads too hot and I have a pathological aversion to scotchlocks - of which there are many. The other thing is that if I unplug the alternator - I have no electrics - which means it's not correctly wired into the system.
On the plus side, the loom is very simple - and I have added a 8 fuse fuse box, a couple of relays for the headlights, a solid state voltage stabiliser, a replacement temp gauge, a volt meter in place of ammeter and an electronic flasher unit. I have also fitted a multiplug connector in the loom by the dash, so in future I can remove the dash by just taking out the bolts and unplugging the connector - no need to rewire every time.
Hopefully the last bits will turn up on Wed, and the wiring will be complete thursday - ready for a shakedown run this weekend to make sure everything is tickety-boo for the trip up to Commerland the following week.
