What about the Voltage Regulator ? Where's it located on my car and do you think it needs to be changed also? What are some known trouble issues that confirm that the Voltage Regulator is done for?

Also is Kaehler (KAE) Overload Protection Relay a good one to go with? ******** has it on their site for $56.23, I just thought i'd ask if its a good brand.

Thanks
