Re: SD> GLHS power loss light and 18 volts
I have seen people buy the self exciting GM style ones and wire them up to bypass the OEM ones. That style of regulator is so cheap and so plentiful I have never seen a reason why to change out the PM or LM to fix the issue.

Re: SD> GLHS power loss light and 18 volts
I thought I had the regulator portion of my computer go, but it turned out to be the shunt (wire that goes to the brush itself), causing to not to charge. The real point however is when I went to an alternator/starter guy he had this little external regulator that bolted right on to the back back of the alternator and essentially got rid of the internal one from the computer. ___REMOVE-FOOTER-WHEN-REPLYING_ ShelbyDodge mailing list ShelbyDodge@imagilist.com http://www.imagilist.com/mailman/listinfo/shelbydodge
Re: SD> GLHS power loss light and 18 volts
Sounds like your alternator is going "full-field" or the LM has lost its reference to ground. The power module drives the field current of the alternator but the logic module is what measures the system voltage and determines how hard to drive the fields. The field terminals are the two small ones on the alternator. One is tied directly to the ASD relay output (battery voltage) and the other is driven towards ground by the PM (the closer to 0V it is, the more current the alternator puts out). If the driver in the PM has failed (shorted) or the wiring between the PM and the alternator field is shorted to ground or the alternator field has an internal short, the alternator will put out as much current as it can. The battery voltage will vary consistently with engine RPM and the voltage across the two field terminals on the alternator will be at about the same voltage as the battery. If the logic module's ground is floating a few volts above the rest of the vehicle, the charging voltage will increase by that amount. The LM gets its ground through a bolt at the fuel rail. In this case, the voltage across the field terminals will decrease with engine RPM. All that said, it is not good for the electronics to operate at such high voltages for long.

Re: SD> GLHS power loss light and 18 volts
Shorted regulator wires can definately cause overcharging... Checking for shorts is a good tip for people that have overcharging issues. Usually a bad regulator in the PM will stop the alternator from charging and the voltage will be 12v or less. A quick way to know if the alternator is charging without any kind of meter is to put a screwdriver on the back side of it. If it is charging it will stick to the alternator due to the magnetic field that the coils create. For your own safety, hold only the plastic portion while doing this and make sure you don't touch the actual terminals (just the case). -Rich On Wed, 14 Jul 2010, Stefan Mullikin wrote: > Date: Wed, 14 Jul 2010 12:55:24 -0700 > From: Stefan Mullikin > To: "rapid...@aol.com" > Cc: "shelbydodge@imagilist.com" > Subject: Re: SD> GLHS power loss light and 18 volts > > On my Sundance that did the same thing, I had to replace the alternator, the > power module, fix the grounds under the power module and clean the pins on > the computer. > > That seemed to have solved the problem. > > Stefan > > On Jul 14, 2010, at 11:36 AM, rapid...@aol.com wrote: > >> I've had it happen with a bad inside the kick panel computer also.

Re: SD> GLHS power loss light and 18 volts
On my Sundance that did the same thing, I had to replace the alternator, the power module, fix the grounds under the power module and clean the pins on the computer. That seemed to have solved the problem. Stefan On Jul 14, 2010, at 11:36 AM, rapid...@aol.com wrote: > I've had it happen with a bad inside the kick panel computer also.

Re: SD> GLHS power loss light and 18 volts
I've had it happen with a bad inside the kick panel computer also. I have one now that if I put it in the Shelby Lancer it will peg the volt meter and if I switch it with the MP computer (that's the only replacement I could find) it charge's normally. I too had a the old type regulator (and it worked fine) but i wanted the stock look under the hood. Roy In a message dated 7/14/2010 12:24:39 P.M.

Re: SD> GLHS power loss light and 18 volts
The voltage regulator is in the power module under the hood (beside the battery) These are known to go, especially if your alternator has wonky outputs. I actually hooked up an external voltage regulator from a 70's Mopar since they are quite a bit more robust and new or reman power modules are getting hard to come by. You can try the Chrysler dealer, but I think they are NS1. A quick scan of ebay brought up 1 or 2.

Re: SD> GLHS power loss light and 18 volts
Had this problem on my GLHS replaced several parts (power module, computer, alternator) with no luck, and so took it to the dealer who again replace the power module, but guaranteed that was the fix. When it failed again days later they got to figure it out on their nickel. Turned out there was a failing wire in the wiring harness. They replaced that and it worked great. Hope this helps .Jim ___REMOVE-FOOTER-WHEN-REPLYING_ ShelbyDodge mailing list ShelbyDodge@imagilist.com http://www.imagilist.com/mailman/listinfo/shelbydodge
Re: SD> GLHS power loss light and 18 volts
I think 1/2 is controlled with the inside computer and 1/2 with the power module under the hood. I can't tell you which one it can be. On my Shelby Lancer I had to replace both to get the volts down.
