bad diode ripple from the alternator ..... Posted by jak [Email] (#195) [Profile/Gallery] (more from jak) on Thu, 10 Oct 2002 00:58:15 In Reply to: Weird voltage boost at random, Dudah, Wed, 9 Oct 2002 22:06:49 Members do not see ads below this line. - Help Keep This Site Online - Signup |
can fool engine managment & abs
try changing the brush pack first
also check your ground to the alternator & pos conections at the starter I usually check circuite like this using a volt meter with one lead at either end of the wire & look for voltage drops under a load
diode ripple causes an AC signal to get out into the system which controll modules can mistake for AC inputs from sensors that return frequencies to the module
good luck
