Battery charger question for johnnieb...

I'm going to make sure that third wire is safely taped up and I'll take those voltage measurements and check the capacitor for reference. I don't plan to use the
3rd wire at this time (if it aint broke - don't fix it). Again, thanks everyone for all the help - RAY

Do you have a picture of the wiring on that receptacle? Mine has 4 wires
red
black
grey
blue with a fuse holder

Yes

Hogasm,

Attached is a picture of a 3-Pin receptacle used on 48V RXV carts.
Is this the receptacle you are talking about?

That is the one

I think the original cap. is round, but this one is oval. I have the charger buttoned up for now, but will make those voltage measurements later. At least the charger is working to some degree and I no longer have to use jumper cables to charge (I installed the cord from the "QE" into this one). Oh, and by the way, this "QE" cord has a third wire, which I taped off and marked as "extra wire". I believe this may have been used as a "sense" wire in the "QE" to eliminate the voltage drop in the charging wire. Is this extra wire of any use in my application?? Thanks, you've been a great help - RAY

FWIW, My PowerWise 28115 G01 is 20 uF, 370 volt.

Let me see if I've got this straight:
You've got a 84 Marathon resistor cart that was modified to a 48V controller cart and somebody gave you a 48V PowerWise QE that may or may not work and you are trying to install a 48V RXV charger receptacle on the Marathon so you can use the 48V charger, but don't know where the wires go.

On an RXV, the Black wire goes to B-. The Red and Grey go to B+. I have no idea where the Blue wire goes.

Thank you I will wire it that way
