Hi, The wires that go to the switches are usually attached using a spade lug that can get loose over time. Take the drill apart carefully, gently tug on the wires one at a time, and pinch the "female" part of any that seem loose to you.

If the generator has been sitting for a long time or was shut off with the load connected it has likely lost the residual magnetism that is required to excite the winding. This is a common problem. Always disconnect the load from the generator before stopping the engine!
The generator needs to be flashed. There are several was to achieve this, but safest would be to use an electric drill.
Connect an older style portable 120 volt drill to the running generator.
Make sure the drill is in forward not reverse
With the switch depressed rotate by hand the chuck of the drill in reverse
careful, the generator will flash, power up and rotate the drill in the forward direction..
Hope this helps?
Careful the generator will flash the windings and power up the drill
If you want to do this job yourself, it depends entirely on your ability. If you're happy pulling apart and assembling dog gears & layshafts then go for it. Take a look at this explanation of gears on youtube to see what you are letting yourself in for.
The likelihood is that something to do with the reverse shaft (the transfer of motion form the gear stick) , or reverse idler gear (usually teeth are stripped) is causing the problem. The parts are generally cheap but the labour to fit them isn't.
There is a little less labour costs in fitting a new gearbox but higher cost in the box itself. So it comes down to economics, do it yourself is cheapest.
Rebuilding the gearbox? Is the vehicle worth it? Is it a vehicle that you can't get a new transmission for? (Depending on the age and worth of the vehicle personally I'd buy a rebuilt transmission).
Buy a new box? Is the car so old that it may need a compete gearbox renewal? ... and if you invested in the cost of a new fitted box, would it be worth it?
I can't answer these questions for you, it's one for you and your bank manager to discuss.
You didn't indicate the KW, are they equal? The power factor and load should be shared between gens equal. The power factor cos is off because the synchronization is off and one gen is pushing the other by a slight phas eangle displacement. You need to check parallel settings and reverse current relay, as it should detect this. I assume voltages are the same on the buss from each unit, when not operated together
I am assuming that you mean the generator head from the engine. If this is so, 1st remove the end cover from the gen. head. You will see a bolt that goes through the rotor shaft to the engine shaft. The engine his a tapered shaft, that the gen head bolts to. 2) Remove the long bolt from the rotor shaft. 3) Remove the 4 long bolts that hold the housing ends together. 4) cut a length of rod that is smaller in diameter than the rotor shaft bolt and about 1/2 inch shorter. This will be used as a push rod to separate the engine shaft from the rotor shaft. 5) There are threads at the beginning(inside) of the rotor shaft. Most likely metric. Find the right size bolt, approx. 1" long. Screw in until contact with the push rod. (If possible, use an impact wrench to make it easy.) Tighten til the shafts "pop loose." One suggestion to keep the engine from rotating while doing this is to remove the spark plug, stick a length of small rope down the hole, leaving some hanging out, rotate engine until piston packs against the rope and stops the rotation. 6)now that the gen head is removed, the engine mounting end can be removed. Good luck.
Make sure the ignition is off (remove key if applicable). Try to manually rotate the auger in the reverse of normal rotation....a small pry bar may help to help it along but try not to bend anything. Between the bar and working the auger back and forth it should loosen enough to come free. If it's REALLY stuck you may even need to chisel some of the chip to get it moving.
No they are right handed thread just correded on. What I would try is heating the bolt up then spraying W.D. 40 on it let it set for 5 mins then try breaking it loose. Just one thing spray the W.D. 40 while its hot but not near a flame.
