Help! Now I have TOO much power!! I'll try to explain this one.I had my(bad)alt.rewound to a 80 amp.while that was being done I put in a new alt. so i could go to Honda Hoot.It ran fine(14/14.1) volts no problem even with all my extra lights,when I returned my rebuilt 80 amp.alt.was done so I put it in.It ran great(14/14.1) volts for 2/3 days then It started climing to 15.6 then next day to 16.5 then a day later to 18.5/and now i have a new Westco sealed battery with a bulge on the side.I took it out and i was sure the Voltage Regulater/rectifier was
bad.The shop i had the work done at said he checked it out and everything was fine nothing wrong with anything in alt.He said they was something wrong in my 93 SE ie;bad ground ,short in wiring,bad battery on & on & etc.I put new alt. back on today and NO PROBLEM (14/14.1) If it's NOT the voltage Regulator is it something in 80 amp. alt getting to hot causing the high volts or a short,bad ground ? I guess I dont understand why if the volts are down in limits with stock alt. why not with the rebuilt 80 amp alt.If you have any ideas or help I would appreciate it.I need some help from my friends I not sure about what im being told by the repair shop here! thank you!!P;S He told me he shipped my alt. to someone in Florida who rebuids Gold Wing ALT.to(80amps)so i am sure that guy knows what he is doing!

Your Rectifier converts the generated A.C. voltage to D.C. current and the Regulator keeps that within specified parameters. Sounds to me like your Regulator is not doing the job.

Hi Dennis

You have a problem with the ground connection to the regulator. I have seen this happen on a friends Yamaha XS1100 blowing out all the bulbs. The regulator tries to keep the voltage at a 14.4 volt level referred to ground. If you have a faulty ground connection you will have a voltage drop along this cable. This leads to the regulator having it's reference above ground ( as much as this voltage drop is ). So the regulator is still keeping the voltage at a 14.4 volt level abovr it's reference which now is higher than your ground level. All other eletric parts see a voltage with reference to ground which now is higher than it is used to be. I hope this is somehow understandable. So look for the ground connections at your alt and regulator.

The regulator is internal in the GL1500 alternator. Your problem is with the regulator in the "80 amp" alternator. When you use your stock alternator, the regulator inside it works as it should. When you use the "80 amp" alternator, the regulator inside it is faulty. The case of the alternator is at ground reference because it is bolted to the engine. Don't look for anything, send the faulty "80 amp" back.
