I just picked up a ext efi 580 deluxe. When I start it it runs great for like 15 minutes then it wont rev out. when i put the battery charger on it it starts right up. I checked the voltage at the battery and it bounces from 5 to 7 volts, but when i rev it up the light gets brighter and the voltage in the battery stays the same. I checked all the fuses and grounds and their all good. Then i let it set over night and the battery reads 12.5 volts. If anybody has any ideas on whats going let be know, cause i just got some snow.

If you rev it and the battery stays at 5 to 7 volts, the charging system isn't working correctly. Charging systems put out 13 to 14V whan they charge.

I've been looking around and it seems it might be the regulator or the stator. Does anyone have the numbers for ohm's on the stator or the regulator? Thanks.
