I had some interesting electrical glitches with no 24 over the end of the summer:

Tacho & speedo bouncing, a couple of failed starts, misbehaving alarm etc and I tracked it down eventually to weak earthing.

Since then the car has been in the garage for 2m or so, where I’ve rewired the front end. I took the opportunity to review some of my early work (with hindsight & more experience I wanted to do better). So I have significantly rewired the front end, with new fuse & relay boxes, and new earth bus (great bit of kit from car-builders) and all seems great again. The most significant step however was the insertion of an earth cable from the front to the rear of the car, making a direct and good link to the cable coming off the battery. This seems to have worked around the problems and I now have a really good earth connection in all three compartments of the chassis.

I share this because I guess it may become an issue with the 3-part chassis not always earthing back as far as the engine area as the joints between chassis components age or become dirty. Its a simple fix and seems to have done the job nicely, as well as allowing me to tidy up some previous messy work.

Back on the road again!

ADMIN EDIT: Thanks for sharing this; I think this will be an issue on the single chassis cars as well, last time I took mine out I had all sorts of issues with the instruments and every so often when I “booted it” with the headlights on it blew the fuse!! Chris
