Try contacting Nixon Power Services in TN. If they cannot help, you take the old rectifier out, note wiring. A rectifier is nothing special as long as it is the same current rating, if the part is truly obsolete then a good electrnic supply house can give you an equiv

Why will it not strike an ark but it will idle up like it is supposed to. Found a blown fuse (replaced it) and the rheostat,.same problem blew fuse again

first, make sure your brushes are making good contact at the slip rings, and the brush connectors are clean and tight.
There are two bridge rectifiers which you will see if you remove the top cover of your machine, test the rectifiers, one of them has probably failed, before testing make sure you mark the wires before you pull them off of the rectifiers you will find a wiring diagram on the inside of one of the panels, the rectifiers are connected across the fuses, they are typically 40 amp/600 volt rectifiers

Check the rectifier to make sure you have AC power on the AC terminal, if you do stator windings are good, if not stator is bad.
If you have AC then check the DC wires on the rectifier, if you do not have battery voltage, change rectifier, if you do suspect wiring / fuses

First start up

Try disconencting the remote start wires between the transfer switch and the generator, if ot still does it you have a bad control board. If it stops, then check the transfer switch for correct wiring of utility and generator power wires, also check with an ohm meter if the run contacts in the transfer switch are closed, that would indicate loss of sensing, or bad board

Although A bit inconvienent this does seem to be the norm for some Kohler units. Actually a small price to pay rather than having a technician come out to replace the ATS control board. There are time delays that could be set longer to keep the unit running longer and may prevent this from happenng

Put new battery on engine thinking that was problem. Engine drew down battery till it won't start engine.

most common problem is the regulator/rectifier going bad. it has a built in diode that changes ac volts to dc & then sends it to the battery.

I have an older model Coleman Powermate 3750 Premium Plus. It is not charging. What do I need to replace?

it can be the voltage regulator that's in the control box or most likely the rectifier in the back side of the gen head it looks like a 1 inch by 1 inch by 3/8 inch black cube with 4 wire posts on it with a hole in the middle for mounting these will go bad in time and are currently avail in electronics stores even radio shack has them make a diagram and mark the wires to where they go on it and mark the rectifier as well they can be cross ref to newer ones as well their just a couple bucks get a spare to have do to a older machine this part is not in the catalog of the manufacture and un avail from them yet they are other places hope this helps

You might check with a Harbor Freight store either locally or on the web. They have several engine sizes available (with overhead valves) that are Chinese made, but the prices are certainly reasonable. You may have to do some adapting to get one to work. Hope this helps!
