Thread: 2005 GP Changing system failure warning came on DIC during a WOT run.

Just like the title says. I did a WOT run and the Changing system failure warning came on the DIC. I cleared the message to check the voltage still at WOT and saw it at 10.90 and dropping, I let off and it shot right back up to 14.8? Any input? alt is failing?

sounds like it is. unless the ripped out wires from the icm have something to do with it.......

Diagnosing the same way I do huh?

this was before that.. lol before the lifter even stated tapping.. btw that bad lifter if you shake it it makes a rattling sound.. lol

ouch thats not so good. yeah looks like its alt time.

i just changed mine the other day, called a local re builder cost 80 bucks from them, vs over a 100 or more everywhere else. the best i could find from a store was advance with a code i got it to 100.

not sure what alt the 05's got but i found a rebuild kit for mine, cs130D alt <<whats on a 98. for 40 bucks, problem is you need a press to get the bearings out of the cars, unless you just swap out the regulator and brushes, VERY EASY LOOKING TO DO BTW. they dont cost a lot either.

Maybe the belt just needs tightening? Maybe going WOT made the belt slip. Slipping belt = no charge.

It has a brand new belt... This car has always had weird electrical issues, scotty probably remembers som of my older posts about them.

found this on rock auto

google starter and alternator re builders in your area. they are far cheaper, and local, if they dont have one in stock you drop yours off, they can re build it in hours most of the time. they are local too so no shipping fees, same day service too.
