RE: 0020102 generac 4800 choke problem/water heater
I have that same Generator and when mine takes a long time to start I shoot some lubricant all over the choke and throttle linkage. Fixes it every time but your issue might be more involved.
I have seen replacement tanks for water heaters online for sale.

RE: Custom/DIY Truck Camper Tie Downs
For the rear I slid 2" sq. tubing in the ends of hitch cross member and attached turnbuckles to the ends. On the front I welded mini 1-1/2" receivers to the frame and slid in sq. tubing and connect turnbuckles to them.

RE: Generator breaker keeps shutting off immediately
While I agree 170VAC is too high, I don't see why that would be tripping a over current device like a breaker. If all down stream loads are off and its tripping there must be a short between that generator breaker and the main breaker of the 120VAC distribution panel. Start tracing wires and opening junction boxes.
Odd the 170V as that is the peak voltage of 120VAC. Is your meter a good one or a cheap harbor freight one?

RE: Electrical question
You need some time delay relays. There are delay on and delay off types all programable.

RE: Using RV generator as backup for house?
I do it all the time. My older toy hauler does not have an automatic transfer switch, it has a outlet in a compartment that I plug my shore power plug in. I installed a 30 amp 240VAC twist lock inlet on the side of my house and ran wires to a 30 amp breaker in my distribution panel. I installed a UL approved interlock kit that wont let me close the generator breaker unless the main breaker is open. I made up a 10 ga. extension cord that has an rv 30 amp male plug on one end and the 30 am 240vac twist lock on the other. I connected the hot terminals together to power up both sides of my panel. I cannot use the electric stove or oven as I only have 120VAC from the generator.

RE: Battery Meter
I have installed a BM2 from ebay. No local display but it is bluetooth to your phone. You can check you voltage from bed and it has data logging that allows you to see your voltage on a graph.
This past weekend I knew from bed that my batteries had died at 3 am for some reason. That reason turned out to be low water.

RE: Basic Question About AC Power Wiring
Status report:
Since the problem is transitory, it’s going to take a long time to test. I got that plug in voltmeter from up thread. I also got a new multimeter for testing.
I tightened every single connection everywhere throughout the power system.
Immediately on startup of the generator for fine tuning, I saw 70 volts on the plug in meter as it cycled on and off about once a second.
No appliances at all were on except he battery charger, which is tiny and a default.
While it was cycling and not harming anything I checked some connections. Once the issue went away, I finally did what I had set out to do which was to adjust the generator speed to get perfect power. It was at 108 which is a little low. The frequency also was low. I moved it around but and ended up at 120v and 58.5Hz, under the load of the electric hot water heater. Good power. I couldn’t get exactly 60Hz without going above 120v so I stayed at those figures.
I haven’t seen the issue again yet, but have only used the microwave very briefly. It hasn’t been air conditioning weather in Florida lately. Ha ha.
I’ll update with new info in case anyone else has a problem like this.
FYI: I have a similar plug in meter and it always reads 105 when the gen is heavily loaded. I checked with a good meter and found that the voltage was really 110. Its a good idea to verify the meter is accurate.

RE: Firman Generator
FYI: My buddy just bought a firman from costco. The first one had cracked plastic on each end of the lifting handle. He returned it and they sent a new one. It too had tiny cracks starting to form near the handle again. Then when started and broken in, it is not running smoothly. Surging under light to no-load conditions. We are gonna use it this weekend and if it doesn't smooth out its going back again.
Edit: this is the 3200/2900 dual fuel model.

RE: Onan surging/backfiring. Brand new fuel pump/filter/carb
Any chance your fuel tank had some water in it? If that water made it to the fuel bowl that would kill the engine. Then if the fuel bowl was not cleaned out the water would taint what ever tests were done with auxiliary fuel supplies. This just happened to my riding mower.

RE: Help! Onan 4K generator refuses to start and stay on
That fuel solenoid will stick closed not allowing fuel to enter the main jet. The reason it runs briefly is because the automatic choke is on enrichening the fuel air mixture, compensating for the lack of fuel going thru the main jet. Any water in the float bowl sits on the bottom and in that solenoid causing corrosion in a short time. I just fixed an Onan with the same issue.
When I disassembled the carb and manually moved the solenoid plunger it moved without restriction.
If I bypass the solenoid will the engine start as long as I use the jumper?
No, the only way to "bypass" it would be to take plunger out of it. The spring keeps it closed until power is applied to it. If you apply 12VDC to it on the bench you should be able to test it.
Did you make sure the holes in the brass piece were free and clear?

I work at a waste water treatment plant and my office window looks out towards the dump station. I must admit its pretty entertaining. Most people that come in here seemingly have never dumped there tanks before.

RE: E rated tire with max psi of 65?
I have general tires Grabber AT on my truck in a 315/75-16 and they are an "E" rated tire at 65 PSI. I too was concerned but trusted their engineers and they have been fine. IF I still had a truck camper I would not have gotten them but the Fifth-wheel tows fine with them.

RE: What's a good battery level monitor?
I use a $30 dollar Bluetooth unit from eBay. BM2 is the model. It has no display and must be viewed on a phone. The best part is I can check my battery voltage without getting out of bed. It stores up to 30 days of data that gets downloaded to the phone when within range. provides really nice graphs as well.

I cant get the clicky to look right.

We race in Las Vegas and routinely take 80 over to 95 in Nevada. No silly trailer speed limits in Nevada and better roads.
