Received my E1074 from Summit today. Looks just like the pics posted by others. Nice to have a drop in pump ready to go on the shelf.

Update... Yes I've been busy working this effort over the past few weeks. Testing and improvements almost complete on the Beta Test version. New PCB being fab'd for Beta Test version and in fab as I write this. Will be reaching out to some of you who you were kind enough to volunteer to be...

I'd assume the ADVR-054 requires a minimum AC voltage across it's to sense leads for it to generate any field voltage. Did you measure what residual AC voltage the new regulator has across it's sense leads? Could be the residual AC voltage the generator puts out is too low for the new regulator...

Just ordered one from Summit too.

Just as a reminder for others reading this thread in the future. NEVER temporarily bypass the QUAD Mod fuse with a jumper unless you are absolutely certain the the Voltage regulator is good. Why? The primary purpose of the fuse is to protect the Quad winding from a shorted out voltage...

I thought I saw 72-5009 in the TM. Can't recheck now. Camping and no laptop.

The big auction site looks to have one for $50. Google 72-5009

Direct sunlight make a huge difference in solar panel output. With indirect sunlight my solar panels put out 150-300 watts. With direct sunlight they kick out 1,700 watts.

Looks like both CR1 and CR2 have been replaced based on the solder blobs and corrosion on their leads in the pics. V5 looks baked too. Ought to be red in color.

Those are the much lower cost types I was suggesting that could be used instead of the pricey ones. They look good to me.

Drop in replacemets for them are available. Crazy expensive though. If you don't care if replacements are drop ins you can get less expensive wire wound resistors and modify the plate as needed to mount and wire them. A replacement for #48 is a FSOT2011E7R500JE. They are available from Mouser...

From top to bottom... R10 thru R13 are the burden resistors for the over current circuit and the %Load Meter circuit. R14 is part of the field flash circuit CR2 is part of the field flash circuit R15 is a current limiting resistor for the Battleshort and AC Interruptor indicator lights CR1 feeds...

No. These... On my 802 they are just above where one of the battery hold down "J" bolts hook into the skid on each side.

Don't forget the two ~1" holes in the skid, one on each side. Just did my 802 and 831's about a month ago.

In 3 phase mode... If you get ~120 VAC at the convenience outlet with S1 in the START position it will indicate a few things. What's likely good and what might be the issue(s) to look into. If you don't get ~120 VAC at the convenience outlet with S1 in the START position will indicate a few...

You are correct. In 120/240 single phase the AC output should be on L1 & L3 and not L1 & L2. The fact that you are getting no AC on L3 but get it on L2 points to a wiring issue. The Frequency meter is driven by L3. Since there is no AC there that explains why it stops working in 120/240...

PCB and firmware updated to support 2 wire remote start command from battery charge controller or other device commanding the genset to start (like other AutoStart option available). Basic relay or switch closure to tell genset to start and produce power. Open relay or switch contact to tell...

Some UPS's have a sensitivity setting on them. If yours have it you may want to set them to be less sensitive. Since UPS's are designed to instantly kick in they will beep when a load kicks on like your heat pump and the line voltage to the UPS dips for a fraction of a second. They are going...

Have you verified with a meter that the voltage at the outlet is 120 volts AC?

You might consider renting or borrowing a 3/4 ton or better truck and a car trailer. The car trailer needs to have brakes. Load the genny onto the car trailer. Chain it down good.
