is there something called a load capacitor on a 1991 350 tbi 3/4 ton suburban? Also why would my volt guage in the vehicle occasionally dip to about 9 volts the rise back up, with or without heat/ac/lights/etc...?
Hi, You might have your alt . checked and take a good look at the wiring make sure you don't have a bare wire somewhere shorting out, good luck Slim
Thanks Slim, checking into it, Tim
