2002 Ford Focus SE ZX5 SPI
I know I’m probably answering my own question here, but I’ve been getting the voltage warning light and dash lights dim/brighten no matter if I’m driving or idling. It comes on and STAYS on until the car is shut off.
I previously noticed the tensioner is likely bad, as the car starts with a squeaky belt and the belt never truly stops squeaking. Its faint but its there. Damp days, forget about it because it will squeak forever. Belt is in good shape so…Bam, obviously the tensioner.
Previous owner put a new alternator and battery in it right before I got it.
Is my tensioner allowing this voltage drop?
