Hi! Just a quick query on a quirky occurrance!

Having finally decided to revive my MK3 1275 S from its winter hibernation, on trying to start it, it cranked over rather slowly, (surprise, surprise!), and after about six or seven goes, it clearly was not going to start, so it was obviously time for a session on the battery charger!

On disconnecting the battery, I noticed the earth lead was warm to the touch, is this normal, or does it signal a bad earth or something else?

I have never experienced this on any car previously, but then it is not something one would neccessarlly notice, unless you actually held the lead, in this instance to move it out of the way to remove the battery from the boot.

Any advice or comments will be appreciated,

Cheers, Dave.

There are several possibilities for this.  If you crank the engine over for a sustained period the lead will get warm.  I note that you said only seven or so.  The starter motor could be a little tired and giving a high resistance.  If you charge the battery and the motor spins freely, this can also be discounted. 

Other possible causes could be a poor earth to the boot floor, poor earth lead or the engine itself is unwilling to turn over freely.

:) If you crank any vehicle with low powered batteries They will get HOT! and very possibly melt any solder in the starter motor. :shock:

Hi guys!

Thanks for the advice. The battery charger worked wonders, she has successfully started and the earth lead remains "cold."

I suspected the non-starting and cranking over caused the problem, but I am grateful for your reassuring advice!

Thanks again, Dave.
