QuestionQUESTION: i got a used alt. and installed it on my 1991 gsxr 1100 because it wasn't putting charge in my batt. and my bright high beam light stays on . when i put it to low beam i can see a lil chage in the indicator light but the hi is still on . right under the ignition my wires get supper hott in 5 min of running time . i unplug the the light fuse and they cool off , but my 2 wires from the alt. get hot and i have over 15 volts to the batt. when running . help if u can , frustrated , leeeoooooo
ANSWER: Hi Leo,
Q: "...i got a used alt. and installed it on my 1991 gsxr 1100 because it wasn't putting charge in my batt.
A: Did the replacement alternator come from the same year, make, and model? Did the replacement alternator test good? Chance are it was good and another system component is defective.
Q: "...and my bright high beam light stays on . when i put it to low beam i can see a lil chage in the indicator light but the hi is still on . right under the ignition my wires get supper hott in 5 min of running time . i unplug the the light fuse and they cool off
A: The charging system components need to be tested. Charging output voltage and current need to be measured. Check all electrical connectors for clean, corrosion free, and tightly fastened connections.
Corrosion causes problems as described. Water shorting is another problem. Use dielectric grease on electrical connectors to help prevent corrosion and shorting from washing and rain water.
Q: "...but my 2 wires from the alt. get hot and i have over 15 volts to the batt. when running .
A: 15 VDC at the battery is good. This voltage is within service limits. Generally, between 13 and 17 volts is common/good charging output voltage among brands.
The two altenator wires may get warm/hot due to some resistance in the system, build up of corrosion, the process of producing electricity, and disipating excessive current in the form of heat energy.
If the wire's insulation or covering appears discolored/burned, brittle, melted, or too hot to touch, a problem exists and needs to be inspected.

QUESTION: how can i test the alt. myself ? it only has two wires out of it . the used alt i put on has the right oem numbers on it . when my old one went bad my bright lights stayed on with my bright indicator light to . now i cant get my low beam to work . did my old alt. fry something . and if my new alt. is putting out too many volts can that keep my bright on as well ? omg i hate electical problems !!!!
AnswerTesting is easy, but you have to read the instructions. Get a copy of the service manual. The manual has illustrated procedures for testing and repairsing your motorcycle. The manual will pay for itself with the first work you perform.
The old alternator may have damaged other parts. I cannot tell without being there to inspect the GSX-R and performing a few tests.
Excessive voltage will blow bulbs. The old alternator's regulator may have put out excessive voltage as it failed.
