Alternator change now got an issue

Thanks reckon your along the right track. The fuse that is smoking is the same factory rating however I could not get one so bastardised one to fit and it is not a tight fitting female to male so think it may not be spreading the current evenly across the fuse hence not blowing but getting hot?

Thanks Nick appreciate it, trying to sort a proper replacement fuse

Cheers

Hi, I don't know what type of fuses you have, if they are glass fuses there are two different lengths being 28mm and 32mm. If the shorter fuse is used in the longer ones holder there is not enough contact area and it overheats. Rover P6s suffer with this. The longer fuses are difficult to get hold of because they are older and newer ones are the ones being made only. If the fuses are ceramic with a pointed end they are reliant on being quite heavily sprung to maintain continuity and are prone to ending up with dirty contact areas making matters worse. You would be best advised to convert the existing fuse holder to blade type, they give less problems and are readily available.

The ones either side are smaller blade width

It is 100amp and sadly I don't have the one I pulled

with it running with the new alternator its only charging at 12.8 volts ? was / is the battery flat that's not right is should be high 13's to mid 14 volts have you left a earth lead of any where if not put a jump lead to the body and then on to the body of the alternator and see if the voltage goes up with it running if it does the earth is not good enough this could cause it to put more current through the wireing and make things wires etc hot

Battery totally dead. Will check the earth tomorrow. It's a curse word when work interferes with what want to do lol
