The fan ran a second or so and stopped. Now my amp doesnt show charging when I increase rpm as usual. It just stays in a fixed postion. Lights on make it show discharge but reving does nothing. Anyone got an idea?? I checked fuses and everything else my pea brain allowed. Nothing..need some experienced help. | | | | | Joined: Jan 2000 Posts: 591 'Bolter | | 'Bolter Joined: Jan 2000 Posts: 591 | Can't say for sure, but considering that it "froze" after the heater fan abruptly stopping and it does show a discharge with the lights on: my first inclination would be to check if a fuse or link in the charging circuit is blown. The meter apparently is doing what it should if something inhibited charging. | | | | | Joined: Dec 2007 Posts: 30 Apprentice | | Apprentice Joined: Dec 2007 Posts: 30 | Thanks Donsz,
I did check all my fuses right off but none are blown. That heater motor fan has been rubbing on the housing and I think it finally stuck and stopped spinning. With that resistance, I would have thought that would have blown the heater element fuse but it is good too. | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | So your meter isn't actually frozen but the generator will not charge? If you don't know the answer then you have to start there. With the engine running well above idle, you should have somewhere around 7.2 v at the bat terminal on the regulator. | | | | | Joined: Dec 2007 Posts: 30 Apprentice | | Apprentice Joined: Dec 2007 Posts: 30 | YOur right Truckernix..it isnt actually frozen as in wont move. Its just not chargeing as it usually does and it started doing this when I turned on the heater yesterday. Since then by the way the heater fan will not turn at all. I will check the generator but I just do know why it would stop charging at the precise moment I hit the heater switch. Maybe co-incidence.. | | | | | Joined: Dec 2007 Posts: 30 Apprentice | | Apprentice Joined: Dec 2007 Posts: 30 | With truck running, I have checked the voltage at the A terminal on the regulator and got zero. Then checked the A terminal on the gen and go zero then checked the coil and got correct RPM and Dwell but big fat zero on voltage SO I reckon my generator is shot. Does that sound correct? | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | I don't understand how you read zero on your coil but let's leave that one. I hope that your test meter is OK. With the motor running, if you place a very temporary ground on the field at the generator, that should cause the A terminal on the generator to rise in voltage. That would indicate that the generator may be OK. You don't want to leave the ground on very long because on a healthy unloaded generator, the voltage can go to 20 volts. | | |
