TVRs wonderful electrics

I've been chasing the reason my voltmeter drops when switching load on. The gauge shows just over 13v with no load and drops to just over 12v with everything turned on!

New battery (even though the old one tested ok) and change of alternator and still the same.

I then checked the alternator output voltage and that is 14.1/14.2v no matter what load, then checked at the battery (in the boot) and that is the same!

so looks like there will be some dirty connections - will have to see if I can borrow a thermal camera

T.A.D.T.S.

must be that They All Are Wired Incorrectly too

I'm only a little worried as last year in the heat of Le Mans the fuse/relay box started to melt. Since then I've fitted a modern Focus one so thought I'd fixed the problem but obviously not. Some time in the near future I'll take the dash out and remove the redundant wires and reterminate the rest. As well as sorting out the heater system.

Just in the process of doing this
