generator auto start

If you can't find the fuse on the wiring diagram (Coach Assist), my guess is that it would be close to the AGS module. Where that is, I don't know.  Maybe check the front run bay for a fuse / circuit breaker.

Cloyd,
Terminal #3 on the AGS is battery voltage and terminal #4 is Gnd. The green ready LED should flash if you have >8v between the 2 terminals. If you don't, the fuse (5a or less) should be  on the red wire between terminal #3 and where it picks up battery voltage. All this is in the front electrical bay.

I'm waiting for things to get a little warmer and drier before tracing the power. It would sure be sweet to see that green light come on.

OK, I have 14 volts on terminal 3 and a good ground on terminal 4 but no green light. Any ideas?

Could be a bad AGS module; the Magnum manual I looked at on line had a pretty good troubleshooting section if I recall.

Cloyd,

I'm assuming you have the AGS unit with the dials running along the top of it (ME AGS). If so, the Ready LED (on your right as you look at unit) should be on. If not, turn the unit off, then enable it to reset it, per the manual. The Status LED (on your left) won't light until generator start has been attempted.

If you have the AGS unit that has no dials across the top of the unit (ME AGS-N) the Ready LED should be lit if if power is applied and the temp sensor is connected. If not connected the LED will flash. The Status LED will be Red or Green, depending on generator status.

I loaded the appropriate manuals to Coach Assist this AM.

Since you've verified that 12V is present, the only thoughts that come to mind is to verify that the 12V powering the AGS is from the same battery set as the generator start voltage. If that is OK it would seem you may have a faulty AGS unit. A call to Magnum 425-353-8833 would be my next step.

Cloyd,
Ignore my comment about battery hookup. The AGS should be sensing the House battery voltage and the Geni start should be off the Chassis units. As mentioned in an earlier post, Monaco may have wired your coach backwards with AGS sensing Chassis and Geni start from house.
Sorry for the confusion (on my part).
