97 GTX blows 5 amp fuse

[petey]

Why would a 97 GTX keep blowing the 5Amp fuse.


If I replace it, it will not pop when its dormant, push the start/stop 2x to activate the gauges, or when you put the lanyard on.

It will pop after it cranks over 2-3 times or even IIRC when the battery was weak and could not crank over the engine. It only seems to pop when you engage the starter.

When I get home I will see what happens when I disconnect the stator and/or rectifier. I just wanted to see if any one had any other ideas.

Disconnect the VTS and see if it stops. Bills86e

It does not have VTS

dont unplug the stator, but unplug (either red and/or yellow, then hit start button) the yellow wires and red wire at the rectifier.

Well with the 3 yellow and 1 red wire(s) unplugged it sill pops the fuse.

Could it be the Start stop switch shorting out?


Last year I did have a problem with a loose connection at the starter solenoid too. I had to take the plug apart and tighten the metal connection. But right now I have to run to AutoZone to stock up on 5amp fuses.

nope, its yuor mpem.

nope, its yuor mpem.

Even though it will not blow the fuse when the mpem is dormant, activated with the start/stop button 2x, or with the lanyard? You can even scroll through all of display options fine.

Another Discussion

There is another discussion on the 5amp fuse blowing constantly, and they were looking at a diode inside the box. There are pictures of what I am talking about with some other symptoms that you may want to check out. It was a pretty informative thread about the subject. You should have a look at that one to see if there are similarities (sp) with your issue. It's worth a look.

Here is the name of the thread that has the discussion in it.

Well I got it running! I disconnected the starting relay (solenoid) and pushed the start/stop button and naturally nothing happened; the fuse didn’t blow either. I plugged it back in and it cranked for longer time before it blew the fuse.

For the heck of it I swapped the relays between the XP and the GTX and the GTX started right up. The XP just clicked a few times, and had to be coaxed to start. I'm thinking I may go ahead and replace the wire harness in the rear electrical box and the relay just to be on the safe side.


I did have to get towed in today though, but that was because I sucked the tow rope into the pump.
