I have a bad stator ,need to replace it . Anyone have any suggestions on how to repair the charging system without pulling the engine ? Any helpful instructions or photos for removing the engine greatly appreciated . Thank You

If you wish to avoid removing the engine, you may want to look at the 'Poorboy Alternator' conversion.
It's an external small automobile alternator. Some GL1200 owners have made the switch.

How did you determine the stator is bad. Have you done the basic ohm meter checks & voltage checks. You can find these checks on this site, but the following is basically the same. To check the stator while still in the bike. Disconnect the small connector about 6 inches out from the rear of the stator that connects with your bike wiring harness, just in front of the battery (this is the most common problem area).
1. With an ohm meter, check between all three yellow leads (coming from the stator), you should have low resistance, about the same on each test. 2. Now check each yellow wire from the stator to ground, the checks should be no connection to ground, open. If this checks OK, now with the circuit open, 3. Fire up the bike, and rev it up to around 2000 rpms, now check for AC voltage between each of the three legs. you should have approximately the same voltage with each leg (30 to 50 vac). If every thing checks OK as I have stated, your stator is probably OK. A good regulator is what changes the high AC voltage down to around 14VDC. NOTE: I have not come across a bad stator myself, only bad connectors or burned wires and connectors or a regulator.
Now your problem is going to be in your connectors, burnt wires or bad voltage regulator, up by your left knee. The connector for the regulator may be a problem as well.
What I have done to correct my charging problem, I have run new yellow wires, outside of the bike wiring harness, the next size larger from stock wire, and then soldered the connections and taped with a rubber insulating tape and then regular electrical tape over that to keep the insulator tape in place. Replace the regulator with a known good one that works, NOTE: You must have a regulator that is for your particular bike, LTD or Aspencade or interstate. When soldering or crimping to the original wires, make sure you have removed or clipped off any burnt or dark colored wire near the ends. You need a good clean wire when soldering. Use rosen core solder A good soldered connection is much better that a crimp, a crimp can corrode and develop heat and high current. Down side of this, in the future, you will have to cut the joint out in case of any problems, so leave a little slack in the new wires you have added.
Hope this helps anyone that maybe have charging problems. I have done this fix to the three 85 LTD's that I have owned, each having charging problems. I pick them up and bring them back to life. The GL1200 is a great reliable bike, but being 25+yrs old, you have to keep the basic maintenance up.
Good luck.

I read the reply about testing the stator using an ohm meter. My father-in-law has a 86 interstate that won't charge. He was told it was the stator. I checked the stator as you mentioned and you said look for low resistance. I got 800ohms on each leg and each were open to ground. My question is , is 800 low enough or is supposed to be lower? I would love to think that it is a regulator or rectifier rather than a stator. By the way , I've been lurking on here for awhile enjoying the "sights and sounds" as it were. Great site and you guys are quite knowledgeable. Thanks for any help.

As I remember,I used a Digital Volt/Ohm meter...Between each and any pair of yellow wires,my stator measured right close to 3.5 ohms....Nowhere near the 800 your indicating....

Here's another post to read through...viewtopic.php?f=5&t=11343

Thanks for the quick reply and the info. At 800ohms, it sounds fried to me. Now I can tell my father-in-law that he has a lot of work to do.....
