HF Predator mod to parallel
Hello all. First time posting and impressed with the help on this forum. I'm trying to re-wire a HF generator to parallel. I have tried many things I found on this site as well as others and I just...

If you search the Chinese 3000w generator thread
There is modification drawing and info for paralleling the windings
As MFG it is 240v center tapped for (2) 120 legs
The rewire is Not red with black, and the two whites
The the rewire mod is red wire connected with the white wire from the black leg,
And black wire connected with white wire from red leg
This puts the two windings in phase parallel,
(You need to think of this as two feeds laid out side by side, 1,2-3,4 You are going to pick up 3&4 and place them on top of 1&2, 3 goes on 1, 4 goes on 2)
The fact that 2 wires are white, mean nothing to the phasing mod, they are colored what they are for the workers , to make assembly easier and faster,
If MFG here in the states they would all be the same color and numbered
Either pair can be used as the hot and the other pair for neutral,
Then
You must correct the wiring down steam going from terminal block to the circuit breaker and outlet's because OEM wiring will now have hot and neutrals crossed connected, and a circuit breaker in the neutral circuit instead of the hot side,
get a new 25 amp breaker for the hot leg, run your new hot to 25a breaker then from breaker to the rwist lock outlet hot connection,
Run the new neutral to twist lock outlet neutral,
If you want to use the duplex outlets
Run hot wire from terminal block to 15amp breaker then to the duplex outlet,
New neutral to duplex outlet
There was a picture of this mod, some where in the 3000w thread, but it might not be there any more although the wiring instructions text is still there,
Hope this helps , should get you what you want to do
And when done correctly works perfectly, the avr now keeps even better voltage control
