Having trouble to connect the fuse box cables. thanks
THANKS!
Trying to find relay or fuses for exciter wire to alternator. I have to keep going under hood to start up the alternato . 3x today. My Volvo mechanic doesn’t know how to trace it either. 😳 Note: SRS light stays on when the alternator doesn’t kick on. It’s a 1993 940 (no turbo) 192369 miles on it. Thanks for any help.
Hello,
I’m trying to find the relay for the two fuel pumps in my 1993 940. Is it the same relay for both? Where would they be?
Thanks
