callippo Posted May 26, 2011 Share Posted May 26, 2011 alternator wires can catch fire. I had that when I had to come back from Scotland last week. It might have seemed like just a flat battery but it turned out to be just wire that needed replacing. It most me 45 quid. Better than catching fire at 80mph on the M1.

manofstrad Posted May 26, 2011 Share Posted May 26, 2011 I think you are missing a fundamental point about what an alternator does. I know what the alternator does, trust me, take out the battery and the alternator won't work so the battery must power the alternator. Link to comment Share on other sites More sharing options...
Obelix Posted May 26, 2011 Share Posted May 26, 2011 I know what the alternator does, trust me, take out the battery and the alternator won't work so the battery must power the alternator. As I said I think you are confused about what it does and how it does it. An alternator will not usually require a battery to generate power as there will be sufficient residual magnetisation on the rotor to excite the coils.

You can bump start a car with a flat battery. No matter how much power is in the battery, if the alternator has gone, you won't start it. Link to comment Share on other sites More sharing options...

But, what will happen if the battery flat, and the dyno thing bust? Bumping it will only end in a crash, and bigger insurance things. Link to comment Share on other sites More sharing options...
