Motor identification - 1999 Humdinger

jonr3 · 01-22-2020, 12:18 PM

So I picked up a nice 1999 Humdinger and am trying to determine the motor. From what I have seen, 2 different electric motors were available:
1. A standard 3.8 hp electric motor, or
2. An 11-hp 550A electric motor

There is some faded/disolved white lettering on the motor that looks like:
CJ7 ? 400?? (see attached pic)
and a date code of: 4/4/99
and a sticker that says: S7904

There is also a sticker that says "Santiago Golf Car Supply, Orange, CA" but it looks as if they are no longer in business.

Anyone have any idea which motor this is? I think it is probably the standard motor but that's just a guess. Although, it is equipped with the Curtis 550A controller...

Can you take a picture of the whole motor? Those numbers are probably just production numbers put on by the factory that built the motor and are probably meaningless.
If there isn't a bigger sticker with a Part number or Model number or manufacturer name, then the only way to know is going to be from looking at the entire motor.
The standard Club Car series motor used during that time would have a big white Club Car sticker on it and a Club Car part number, along with some other info.

Another thing to do is measure the length of the motor. A jump from 4 hp to 11 hp is not easily doable within the same motor case. A motor with that much power would likely be longer than a standard series cart motor.

I'll try to get a couple of decent pics of the motor but there is a lot of stuff in the way with no easy access except to jack up the cart and crawl under. I'll also try to get some measurements while I'm at it.

I couldn't find any other stickers except for the one showing the connections. Didn't see any other markings stamped on it either. The motor measures approx. 10.5 inches long from the red lines indicated on the photo...

I'd say that's probably the 11hp motor.
The internal cooling fan and vented brush cap indicate it's made to produce a lot of power, and that means heat.

Cool! Thanks!!!

So... if what I have seen is correct, then this Humdinger with the optional stereo, winch, and motor, would have had a price tag of $18,945.00 in 1999? Yikes!!!

Some of you may have seen these photos that I posted elewhere. They were taken in Las Vegas on a trip in Feb 2001. The photo of the specs might be useful to you.

What's the rest of the frame look like? Is it built on a club car DS frame?
