Hello Remove the three screws at the front upper part of your control panel it is hinged. At the very bottom you will find a line of terminals numbered 13 through 20. For 120 - volt output, connect one jumper between terminals 15 and 16 and the other jumper between terminals 17 and 18. For 240-volt output, connect both jumpers between terminals 16 and 17. Both jumpers should be there they are flat copper plates. YOU MUST DO THIS CORRECTLY OR SERIOUS DAMAGE WILL OCCUR. P.S. I will be out of town for about a week if you still need a wiring diagram I have one just need to find it.

If you want 220V single phase 3 wire, you can take the neutral from terminals 16-17 where the jumper plates are connected. I run my whole house this way using a transfer switch between the meter and breaker panel.

I own a pe95k as well, just rebuilt the willys...new brushes..gauges that were needed..runs like a top. How exactly do I hook up the leads to get the single phase 220..you mention pulling the neutral out of the block @ 16/17..can you be more specific..using the wiring diagram or ? I have all of the factory manuals plus the attachment 1 for the I and K version. I know how to get single 110V...and "the european 220" but how do I get the three wire setup you describe? Thanks, Nick

I also own a PE-95K, and it is easy to set it up for 240 volts. The first thing to do is strap it for 240 volts as described above. The 15 to 16, and 17 to 18 jumpers should be removed, then place both jumpers between 16 and 17. This will get you 240 volts. Now add another output wire to 16. This will be your neutral. You will now have three wires coming out of the control box. The two hot wires connect to 13 and 14. The neutral connects to 16. Note: This is NOT a ground! I would NOT use the terminal strip below the control box to connect the generator to your load. Instead replace it with something more modern. I used an air conditioner disconnect box. You should measure 240 volts from 13 to 14, and 120 volts from 13 to 16, and also from 14 to 16. If can send you a picture if you wish.

I have the factory manuals, but I am missing the attachment for the K version. I would appreciate it if you could scan it and send me a copy. My email address is skitch at nycap.rr.com

Thanks, Kevin

Thank you for your offer of the wiring diagram. I already have the K wiring diagram, and the TM11-904 service manual, but I am missing the rest of the K suppliment. Nick is going to send me a copy.

Thanks again for your offer.

Kevin

I'm not trying to hijack this thread but I need some info if possible. There is a PE-95-K for sale locally and I was wondering what it is worth. It is mounted on an inexpensive trailer, runs good and they are asking $850. What are the going prices? Thanks

I can't give you any information on pricing, but I can tell you a bit about the PE-95. The PE-95K was produced in the early 50's and used a Willy's CJ-3 L4 engine. The generator on mine is a 10Kw, 12.5 Kva Onan 10JWC-1R, and can be wired for 120 volts or 240 volts. The good thing about the PE-95 series is that the engine parts are commonly available from sources such as NAPA, and relatively cheap, at least compared to Onan parts. The bad news is that the Willy's flathead engines were never known for good fuel economy, and this generator is no exception. It will use about 1 gallon per hour running with no load, and about twice that under full load. The decision to buy it should take into consideration your intended usage and how you intend to keep it supplied with fuel during a power outage. In my area, most gas stations do not have backup generators, and finding fuel during a long wide area outage can be a problem. That is why my primary backup system is a 5Kw diesel. If this is to be your only backup generator you may want to consider something more fuel efficient.

In my opinion, if the unit is COMPLETE, has been load bank tested, and is running well, with a trailer, the $850 is not a bad price. As I have found out, even "modestly priced" parts can add up very quickly. It is often more cost effective to buy a functioning unit than try to fix a non-functioning unit. I have a rule of thumb for this situation: If I can test it, and it works well, we can come to an agreement on price. If it doesn't work, I will take it away for free.

My PE-95K was free, the side covers were missing, as well as the gas tank and most of the fuel system. The engine and generator both needed work. I probably have about $500 in parts and a lot of my own labor into the project. It was a fun project getting it running, which was the purpose of bringing it home. You always have to remember that the cost for parts adds up quickly.
