It's Ok, I know how frustrating it can be some times.

When you talk to them, don't let them tell you that you can't change the rotation. A DC motors rotation can be changed by switching the polarity of the field magnets (electro magnets in this case). That can be done by changing the flow of electric ( + an - ) The trick is you can not change the flow through the armature too, if you do, it will still rotate the same direction. That is why just swapping A1 & F1 will not change the rotation. You could achieve the same thing by changing the flow through the armature without changing the flow through the field. I am just not positive I want to tell you how to switch it on the outside, in case I am wrong. I think it probably flows from F2 through to F1 to create the field magnets, and then in A2 and through the brushes to the armature and back out of the other set of brushes through A1 to a ground. You could research reversing DC motors and decide if you want to try or wait till Monday.

Hello, I have been watching this info for some time and it has been very enlighting(sp) i DO NOT want to high jack this thread, however i seem to have some problems when my350 will o2 workhorse, just a lillte turn over when i push pedal, mostly when i drive it for long distance 2 mmiles battery shows 12.7 v after it sets 10 minutes it ok, any suggestions as I said I not want to get in trouble for high jack this thread, so u can tell go take a hike, thank you

Monday the shop said I had wired the generator wrong. I said it was wired in accordance with the 2002 schematic and ran in reverse. They suggested to swap the wires on A1 and A2. I am in GA for four days of "training". So the first available time to externally rewire is Friday afternoon/evening. I will let the board know how that goes. If it works, I will have a cart that is not sync'd with the schematic. Should be a way to do something internally (by the shop) so I can make it like OEM schematic. Should I "worry" about it if it runs OK?

[jiminpa]

if they fix it internally, they would likely just swap A1 & A2 on the inside of the housing. At this point, I'm thinking grab a beer, put it together, ride it and forget it. Might be a good idea to make a note, laminate it, and attach it some place it will stay. You you don't forget or the next guy does not have to go through the headache of finding out the hard way.

Today the results are in. The swap of generator terminals A1 and A2 was a SUCCESS.

The generator now runs in CW rotation and the CART RUNS AGAIN!!!

Whew! It took a LONG time to get this one back on the road. Some of my own doing. Some just bad timing.

Many many thanks to jiminpa for helping me with this repair.

Land Owner, You're Welcome.
Glad that you're back riding the cart again.
