alternator problem help!

[armandovivoni]

hi. I just installed my alternator after having it repaired, and it only lasted for 1 day. my problem is or I should say my doubts about why it damaged again. is cause I just installed a new downpipe that fits MM almost touching the alternator and im thinking this is why it stoped working.

NOTE, It stopped working right after a WOT on 1rst gear and the engine revlimited, exactly when the engine hit the rev limit the alternator died.

so what is it? is it the downpipe too close to the alternator or is it just a poor repair was made ?

thanks/

I know for a fact HEAT KILLS alternators, maybe it got yours but your RPM's and alt dying like that makes me wonder, do you have heat wrap or anything on your downpipe?

 

[armandovivoni]

no heat wrap. I just dont want it to be the downpipe. it a project making a new one. expensive and time consuming.

 

[flyinghighlm]

i thought DSM's are projects I know mine is, did you check your relays and connections, maybe one blew

 

[armandovivoni]

yes i cheked the main fuse. and alternator connections.

you are right dsm's are projects.

but I just finished with a mayor project of fitting a huge turbo and making the downpipe,installing some other things. and now this. arrgh

I know that there are alot of people who have had repeated troubles with alternators that are rebuilt from autozone ect. People also seem to go threw alternators alot when running without heatshields on the turbo, and manifold etc.. So i would first try ether getting heat rap for the down pipe, or develope some sort of heat shield for it.

Hope this helps

alternator is on warranty right now. all i can do to isolate heat is to roll the downpipe in thermotek. but the thermotek will be touching the alternator.

you guys think thermotek will work?


does ceramic coat come in a spray can? maybe i can throw ceramic coat on the downpipe and also cover it with thermotake.
