I have a voltage drop at idle...my lights dim and the gauge fluctuates and drops....Then when I hit the gas it goes back to were it's supposed to be.

I have installed a 200 amp PA alternator and it is charging...Also battery is good.

Only at Idle will I have this problem. I did not have this problem before with my 75 amp stock alternator....WTF.

All the connections have been checked over and over...they are all good.

Is it an TPS problem or IDle speed problem???

i had the same prob with udp. I put a charger on my battery over night and just watch the voltage very closely. I try not to idle anywhere for very long either. good luck
