Since I have had the yellow leyland I have been plagued by alternator and battery problems. When I received the car the battery was in the negative earth position (negative terminal to earth) and there it has stayed.

The other night when putting the battery back in, I put it in the wrong way. When I went to connect it up I had connected the positive to the earth and was hooking the negative when there was a large flash. I realised what I had done and changed it back.

When I put it back on the correct way there was no flash or anything.

Is this normal?

Edit: It is still drivable and ok.

How do you know if a car is positive earth or negative earth?

Simon,
Normally the car is negative earth if it has an
alternator fitted.
Its a lot easier if the car is neg earth
i.e.when fitting acessories such as a radio.
I changed my 66 deluxe from pos to neg earth when
I first bought it,it only takes a few minutes.
For anyone thats interested here are the instructions
from minimania site...

If you hook it up back to front, the alternator diodes all conduct to ground and you get a BIG short. Effect on wiring is not pretty....!

I'll say... I put the battery in backwards once and fried the whole lot, including alternator, starter solenoid, ALL the fuses. It put it in backwards because I wasn't paying attention to the terminals. The newer battery I had bought had the electrodes on the opposite side of the battery, so I rotated the battery around until it was the way before (towards the lefthand side on the top). Little did I know that now the electrodes were back to front... LOL!
