Following my "Quick Panic" thread...Not so quick solution & still a bit of a panic!
The problem!
Switch on , start up Runs. Ign warning light stays on & ammeter reads negative (and more so if lights etc on). revving the engine makes no difference, not even a dimming of the warning light..
Wiring checked...all in the right places:
Continuity good from D+ on the swichboard to D on the dynamo.
Continuity good from D+ on the switchboard to cut out D.
Continuity good from S on the switchboard to S(H) on the Dynamo.
with Ign on and engine not running; no 6volts at the dynamo D nor S and I think there should be on one of them???
Is it time to dis assemble the Switchboard & give it a good clean?
The car WAS charging happily on its last run up from Oxfordshire....since then I have "tidied up" some of the wiring, but nothing replaced...some Lego brick connectors replaced with more suitable, wiring fitted properly into clips etc....
Wiring is all "armoured" pattern with decent length unarmoured tails where they go into the switchboard to avoid possible shorting ….
