    Do a little research on your furnace. Find out if it is powered by 110 or 220,...etc.

SOURCE: Furnace runs on utility power but not on back up generator power

Using the Hz meter you can adjust the governor throttle screw to raise or lower the engine speed
to get an optimum 60-62 Hz setting. You may want to load your generator with the most
common load you will be using and then adjust the screw to give you an adjustment within the
60-62 Hz range. If you set it too high, then it means you are running the engine faster than
need be and will add to premature or serious engine damage to the internal parts. It is
mechanically governed to maintain the proper engine speed once it has the standard setting in
place. Do not attempt to adjust this governor throttle adjustment screw without the proper tools
available. You can not do it by ear! If you do not have a Hz meter or tachometer available, then
you can use a conventional electric clock with a sweep hand for seconds. If you plug the clock
into the generator, a proper engine speed would make the clock do a minute in exactly 60
seconds against any other timing device. If the clock takes longer to do a timed minute, then the
engine speed is too slow and you need to raise the engine speed; turn the governor throttle
screw clockwise. On the other hand, if your clock does a minute in less than a normal clock
minute, then you need to lower the engine speed, turn the governor throttle screw counter
clockwise. Now you should have a good setting for your generators frequency setting. It is best
to do a frequency setting before doing any voltage adjustment.
I did this today and my Goodman fired right up after two days of frustration!

SOURCE: install automatic ignition system for a coleman furnace

For sure turn off the power at the breaker!! Now as far as the new board, usually the new board will be a new modified replacement, the wiring will be different from the original. It is very important to follow the installation instruction that come with the new board, if you go step by step, it will be ok. Just don't be surprised when you find that the new one is not exact. It is all in the name of improvement, follow the install manuals, step by step. As a 30 year Heating and cooling tech, it was very worrisome when they started doing this, but as long as you have a board that matches the brand and model of your furnace, it will be ok.
Good Luck,
Paul Gibson

Hello there
It sound alright but You should draw out a wiring diagram on paper first before you tackle the job that way you know you're doing it right.

Good luck Dickson

Generator runs,no power at breakers or output plug,has been started and shutdown under load. 5.7 volts on wires coming from stator. All three wires.this is on a motor home.

have the unit checked by an authorized generator repair shop
if it was operating when shore power came back on there is every possibility that the generator or inverter has been damaged from the lack of synchronization of the sine wave

Trying to driveRHEEM RAMB-036JAZ using a Honda eu2000 generator. How to hook this up?

You have to very careful powering up home appliances on portable generators due to back feed problems to incoming lines. I would recommend getting an experienced electrician to show and explain the problems with what you are considering. Many linemen have been shocked due to backfeed. The real way to perform this is to get the controller that is put on home generating systems such as generac type systems. These automatically isolate line supply from backup power from home generators, thereby eliminating shock hazards to linemen.
If prolonged shortage, you could disconnect the wires into the furnace and install an extension cord from the furnace to the 120 volt plug on the generator. Most fans are powered on gas furnace on 120 volt. Make sure your voltage needed on your furnace before attempting emergency power up. I have seen some furnaces power by 240 volt fan motors. If it is 240 volt then use the 240 plug wired correctly. PS when you get an electrician to help you with the wiring, check out the requirement to provide grounding, to lessen your shock hazard.
Hope this helps.

How can I modify wiring to solve a generator related problem?

A common is basically a ground. If you had to you could run your common to an electric outlet on the ground wire. Not recommended but I have done it and it will work. I'm a southern a/c guy with no oil furnace experience but if your furnace isn't sending 24 volts to the tstat it's not going to matter if it has a common because you will have lost your 24 volts when your a/c is off. If your furnace does send 24 volts to the tstat then I don't see why you could not get the common from the same spot, even if you run your common straight to ground. Good Luck

I recently purchased a Husky 3750 watt generator to ''hook-up'' to my house. The wiring already exists so I figured I would just plug and be good. NOPE! I get it started with ease but when I try to...

Is the house dead??? Did you turn off the main breaker in the house?? It sounds like you are sending voltage to the generator.Do you have a switch that stops the power from going down the street from your generator?? 3700 watts is not a whole house genny, you need more like 6500. 5000 min, unless you are just running the fridge and the lights. Is your "plug" wired into the fusebox through a breaker or straight to the bars? You gotta check these things out.

Where can I find a wiring diagram to install a generator into a boat? I know how to wite the 110 volt side but where do I connect the 12 volt power from the generator into the 12 volt distribution panel?

Installing a generator into a boat is critical to be done correctly. You need to contact the manufacturer of your generator for approval, and wiring diagrams. If done incorrectly (which if you are connecting 12v from gen), you may create eddy fields that can cause galvanic corrosion, not to mention electrical shock hazards.

If your generator isn't marine rated, then don't install it into a boat.

Portable generators can be used, but don't hardwire those into a boat. Just use extension cords to the appliances you want to power.

I can't remember if you plug in the generator to the electric panel first (with power turned to the generator and off of the main line feed) and then start the generator, or start the generator and then...

OK, by talking about a plug, I am assuming you have made a double male plug to hook the generator to the electric panel. This is not really advised, because it is so easy for it to be plugged into an outlet by someone not knowing what it is far, and getting electricuted. Now, away from preaching, and to helping.
It is best to hook it to the generator and then crank it, so you are not dealing with a load when you plug the systems together. When your power is restored, it would be good to install a plug to your electrical box and have it go to a disconnect like is on your outside A/C unit. It moves you away from the hot wires.
Hope your power is on soon!

Wow, you've got an ugly problem. It sounds like you already know that you have to pretty much disassemble these little buggers down to the frame to see anything inside, so I'll say what to look for:

1 - Burned wires in the part of the generator that doesn't move. This is the bit that carries the current shorted out by the mud.

2 - Burned wires in the part that does move. This is the bit that makes the magnetism that makes the electricity. There are also some diodes and MOVs tucked into the end of the plastic insulator

You're likley better off getting some other generator, sorry.
