We, my father and I, were in the process of changing the alternator (the old one froze) http://www.914world.com/bbs2/index.php?act...81&hl=newto914s
We got a rebuilt from autozone, but after putting it in we figured out it had a bad diode(never go to autozone). I ordered another one from a place online I get a lot of parts for my old Benz from. It was cheap. $80 for a bosch rebuild + 20 core charge, they have free shipping, and I usually receive my order the day after I place it(crazy fast). Now I wasn’t there for this, but after my Dad reinstalled the alternator when reconnected the Battery cables the wire harness on the altenator started to fried. By the time he got the wire off the battery again it had completely melted the wire going from the Alt. to the starter, and singed the wires going to the relay board. What might have caused this? I already ordered a new harness from Jeff, but after I change it I don’t want to melt another one. Could it be the wrong amp Alt. It’s a 55 amp Oh, 1.8 block with D-jet Thanks guys Samson |

Thanks Davep for a link to the Classics artical. I think that's it. Yestarday my Dad took off the Alternator and had it check and it was shot. I told him to look for a spark mark and he said it looks like it shorted through the resister, but found no marks on the air guide cover. The VR check out ok.
dmenche914 the guys I ordered the ALT from are thebenzbin.com They don't have a ton for porsches but have just about everything for old Benzs. Overall I've been really happy with them, super fast shipping and cheap Euro parts, but their return policy sucks (IMG:style_emoticons/default/finger.gif) I'm not even sure if they'll take the ALT back. One of those "no return on electrical parts if installed" clauses. Then it could take up to 4 weeks to receive a credit. |
