[DeTomaso] Alternator blues....

[Joseph F. Byrd, Jr.]

Would you have a link to /or some photos of the mounting brackets to see if there is an obvious rigidity/resonance issue?
(might be able to add a stiffener)

All,

Check this out. I have never bothered to look at the alternator while the engine was running before, as it can only be seen from under the car. 

Today I put the car on the lift and had Lori start it up while I filmed it:

Look at how violently it's shaking! You can feel it throughout the car--the engine was smooth on the dyno but there is a vibration now. 

I haven't yet explored to see WHY it's shaking so much. I wonder if the mounting bolt that came with the kit is the wrong diameter and the alternator is loose even when it's tight?

I can easily imagine this kind of motion being responsible for the problems we have been having, don't you?

Mike
