[MiniGT5]

Right I have the following problem

Car wont start cos of flat battery will bump start ok and sometimes start after a run.

Measured battery today 12V but would not start jump started it and it reads 11.7V whats going on there then

Could it be dynamo or or the regulator

hmmn could be a number of things but in the early haynes it tells you how to diagnose the charging system and regulator box by measuring all the diferent voltages at particular engine speeds etc ,if you have any problems or questions (no manual) shout

This all came about because one of the contacts in the regulator box got bent making the circuit go live and smoke come out of the dynamo. I know I have burnet something out just trying to figure out what. Charge light seems so still work ok (i.e. it comes on when the engine is at very low revs goes off at idle.)

I will have to get reading the early haynes manual.
