Vanguard charging?

Postby BLES » Wed Aug 08, 2018 10:29 am

Vanguard 294447-1196-A1 (can't read code)

Not charging battery. 19+ AC volts coming from stator. Battery voltage out of regulator.

I'm thinking regulator, but also THOUGHT AC voltage should have been more like high 20s.???

19V from the stator is fine, the v/r has failed

Bles do you know which alternator stator you have? 19V is only fine if you have the 10 amp system.

With the engine running at 3600 RPM, AC output
should be no less than:
• 28 Volts AC – 5 Amp System
• 40 Volts AC – 9 Amp System
• 20 Volts – 10 Amp System
• 30 Volts – 16 Amp System
• 26 Volts - 20 Amp System

Regulated
5 Amp Black Wire Green Connector 1-5 Amps + DC (Charging)
9 Amp Black Wire Green Connector 1-9 Amps + DC (Charging)
10 Amp 2-Black Wires Yellow Connector 1-10 Amps + DC (Charging)
16 Amp 2-Black Wires Yellow Connector 1-16 Amps + DC (Charging)
20 Amp 2-Yellow Wires White Connector 1-20 Amps + DC (Charging)

The regulator has the 2 yellow wires and connector, as well as the one red wire (797375 I believe). I need to disassemble a bit more as the wires from the stator are hard to see right now. I assume you mean the color of wires from the stator are what determines which stator it is, not the regulator wires.? The IPL for this number only lists the 10-16 amp stator (696458) not the 20 amp so I'm hoping it's the 16.

Correct...The stator is the same on 10 and 16 amp it just that the flywheel magnets are larger for the higher output.

I was working on a vanguard and from the factory or the ipls was wrong from the start of my issues. I had to call Briggs to confirm this and they didn't show the one that was in the machine so I had to change the stator and regulator out. If I am thinking right from 4yrs ago the regulator red wire made a loop into itself or to the starter which is the battery wire on the one I had. They thought from the factory that some stators got missed up on the line and the only fix that the people on the line knew was to hit the stop button and grab the other regulator that fit the stator wires in the result end it wasn't the right one and caused a failure which was below the 20amp that it called for. Might want to check and make sure it is the correct all around reason I say that is I had to do it twice before I found the real issue and what was going on.
