Hello,

Starting to troubleshoot generator not powering anything but I'm curious why this Coach has 2 Breaker Panels. Can someone help me understand the AC Power Path. I do understand the Power Converter (AC to DC) and the MagneTek has the battery charger.

MagneTek 6345 Power Converter - 30 | 15 | 20 | 15 | 20 | 20 Amp Breakers (from left)

This Panel mounted nexted to the MagneTek - 50 | 30 | 20 | 15 | 20 | 20 Amp Breakers (from left)

Mounted above the MagneTek

According to this Thread I should have 2 50 Amp Breakers for 50 Amp Service, I only see 1. The previous owner said no problems plugging into 50 Amp Service.

Is BFlinn181 incorrect in Post #2 in that Thread?

Also in that thread (linked above) he mentioned for that particular Gulf Stream Coach there was no ATS installed. After not being able to find one I thought perhaps I didn't have one either. But as I was taking pictures for this thread I found the ATS I believe under the bed.

I don't know the brand / model yet, need to get in there and clean the label off.

I do have some questions about my generator not being able to power anything in the Coach, it did the first day when I could run the rear A/C unit on generator. I'm not sure if there are breakers in that ATS and I don't understand the 2 breakers on the generator, 1 20 amp and 1 30 amp (30 amp was in the off position). Perhaps I have a bad ATS.

My Battery Control Center - I first thought the ATS or a relay for this was in there.

Generac NP-66G Circuit Breakers - Why 1 30 Amp and 1 20 Amp?

What does the Transfer switch look like and what brand

CoachStreamr · 08-27-2017, 07:27 PM

I may have been editing the post during your reply.

It's the 4th picture from the top in Post #1. Tomorrow, I'll lift the bed and get a better look at it. I don't know the manufacturer and model yet.

CoachStreamr · 08-27-2017, 07:33 PM

I used google images and found

Don't know the exact model of mine but it does look like that label, so maybe Todd Engineering Sales, Inc. in Elkhart, Indiana

I have a different set up but if the generator is not powering anything I would look for breakers on the generator itself first.

I've seen set-ups with two breaker panels when one feeds from AC and one from AC and inverter.

RE: 1996 Gulf Stream Scenic Cruiser 50 Amp, Automatic Transfer Switch, Generator

these generators can have breakers elsewhere on the generator? Our coach doesn't have an inverter, at least I don't think so (nothing in the battery compartments or up front in the Battery Control Center bay or in any interior cabinet).

MikeyRVNW · 08-27-2017, 08:01 PM

When mine stopped powering anything and the house breakers seemed fine I searched my generator and found two breakers both tripped. No problems since. That is where I would start. Then I'd see if everything works on shore power.

CoachStreamr · 08-27-2017, 08:38 PM

on that last picture in Post #1, I did have both those Breakers on (the 20 Amp was the one originally only on), turned both off, then 1 on at a time. I look for more breakers around the generator.

Well, while searching around with google, I found this forum thread here on irv2: http://www.irv2.com/forums/f54/gener...6g-153907.html

Have not had a problem with 120VAC coming up since the install.

I sent Tom17 a pm just to confirm I need to keep holding the Start Button down for 3-5 more seconds after the generator engine starts to keep the field boost circuit going. I may install that kit.

Has worked both times I have tried (once with shore power connected, once without. Hopefully that will help those with Generac NP-66G Generator, mine is propane. THANK YOU @Tom17 !!!!!!!

My Stop button on the generator does not work, the one on the dash does. I can always cut off the propane (the manual has this as a proper procedure for long term storage). I'll look at that stop button issue in the future.

After several seconds, I can here the click in the ATS. Microwave comes on, I can use the Frig on AC and I can turn on rear A/C, this is off the 20 Amp Generator breaker/leg.

I need to have the 30 Amp breaker on for the front A/C, high/low fan works but the breaker gets tripped when the front A/C tries to go on. Any suggestions on that?

Does the front A/C work on shore power?

CoachStreamr · 08-28-2017, 01:18 PM

Yes, on shore power I can run either the Front or Rear but my current dedicated circuit is a 20amp here at the house and I am using the following extension cord so I can't run both at the same time now:

https://www.lowes.com/pd/Utilitech-1...n-Cord/3191731

I had to use that 100' plugged into the Coach's RV 50amp cord (with converter cables) since the RV plug was in the back yard with the septic tank connection, wife wants the Coach parked on the other side off the house.

I try to keep it max at 15 amps though with the included 9" adapter and the outlet. In the future, I will have an electrician install a 30 Amp dedicated RV Plug or maybe a 50 Amp (not sure I need to go through the extra cost for 50 here at home though).

EDIT: Tom sent a PM and said:

You may have a weak breaker that's tripping when the AC compressor kicks on. It pulls a pretty good surge at startup.

Not sure how to test for a weak breaker, probably would just have to replace it. Perhaps someone else has another tip/suggestion.

OK ... from the above, if I understand correctly, you can run the front A/C on a 20 amp shore line with no problem but if on generator, that front A/C trips a 30 amp breaker. Correct ??

Theoretically, the only difference between those paths is the transfer switch.

CoachStreamr · 08-28-2017, 01:37 PM

Yes, on shore power (also using the 100' extension cable, see the reason why above) which is to a 20Amp dedicated circuit, I alternate running the Front and Rear A/C units. On hot days, one day the rear A/C, the next day the front A/C - of course don't even try to run both at the same time with the current shore power setup. I do have the fridge on (AC) and don't use the Microwave.

On Generator, the Front A/C fans won't even work unless the bottom generator breaker (30 Amp) is on. With that breaker on, I can run the front A/C unit's fan on low or high. If I set to Cool and the compressor tries to go on, the bottom 30 Amp generator breaker trips.

The top Breaker on the generator is 20 Amp and can run the Rear A/C even on high. It seems the Microwave and fridge also come off this breaker. I'll have to test with just the bottom 30 Amp breaker on the generator to see if the Microwave and Fridge get AC.

I have a picture of the Generator's breakers in Post #1.

Part of your question was about 2 50 amp breakers and you could see only one. The second picture show a single throw, 2 pole breaker (50 amp) so you do indeed have 2 50 amp breakers as the schematic indicated. MO
