Stator question. I need help with ac voltage.

945 Views 5 Replies 6 Participants Last post by  roscoepc
I have tested the stator at 3000 rpm and I am getting about 35 volts out of all three legs. That is with the three yellow wires discontcted from the voltage regulator. I was told the bike has charging problems. It has a new voltage regulator and a new battery. Do i need to change the stator, I have been told in the past that if all three legs weere with in 5 % of each other the stator was good. I have seen three different numbers that the ac voltage should be. 40 volts ac up to 70 volts ac. What does the honda electronics trouble shooting manual say the minimum voltage shluld be. I do not have a electronis trouble shooting manual.

Thanks in advance for your help.

first, what year/model are we testing? at the top of site, use the search function to find the tutorial "stator testing". it's done on a 1200 but other models similar.

James, the stator voltage readings on the "yellow wires" should read about 50VAC @ 3000 rpm. You have 3 yellow wires A,B,C "A-B=50VAC" "A-C=50VAC", "B-C=50VAC" This 50 vAC is plus or minus a few volts, but if your only getting 35vAC then I'd supect the stator is going south on you.

The Honda manual never addresses voltage. That's just an earmark that the "industry" has come up with.
The test for the stator is pretty straight forward from the manual.
No continuity to ground on any of the three yellow wires.
Continuity between the three yellow wires.

Everything sounds about right to me. But, the stator output is normally tested at higher RPMs. If you can get it up to 50+ volts by raising the RPMs I'd say it was OK. A more relialble charging test is to:
1. Start the bike when warm and at idle test the voltage at the battery.
It should be around 12 volts.
2. Raise the RPMs to 4K with the tester connected. The volts should go to 13.5 volts. If it does you are charging OK.

Hope this helps.
