Can you use the ERIC Charger ON Board? I was planning to buy the Lester Summit II 650 Watt or 1050 Watt and mount them ON Board but could save the money if the ERIC Charger can be used as an ON Board Instead. Can u advise?

Yes, the ERIC can be used as an onboard charger.

You need to run a wire from the Charger Terminal named C3 directly to Controller pin #5.

You cannot use a pull-up resistor, so if this is a cart originally came with an ERIC charger, just cut the Blue wire on Controller pin #5 and run from the Controller directly to the charger C3 terminal.

If the cart originally had an OBC, just cut the blue wire at the OBC 6-pin connector and run the blue wire from the harness side directly to the charger C3 terminal.

Sergio,
I opened up the DC side of the ERIC Charger I am working with. I currently have from the Factory a White Wire on C2, and a Black and Green Wire on C3 from the DC Cordset. Once I remove the cordset exactly how will the wiring be on the DC area? I heard you say that I run a wire from the #5 pin to the C3 but what else will be needed? Any other wires and where will they be attached ? Thank you in advance!

You should not have had anything plugged to the 1/4" male quick connectors: C1, C2 and C3.

The existing DC cord ring terminals should be connected to the screw terminals + and -

I am looking at the specs for the IC-650 so perhaps the ERIC version does not have those?

Can You post a picture of what You are looking at?

Maybe I uploaded them correctly. The ERIC Charger Model # is ICO650-048-CC that I am using.

Sergio, will he need a 10k resistor on the cart side to give 48V to the controller pin so when the charger is off the controller will come out of lockout?

The charger may need to be configured for on-board operation using IDAT software. I don't know how the ERIC charger will respond if the AC power is unplugged and the DC is present at the charger all the time.

That will not work as onboard with Controller interlock without a relay.

I guess that is why Club Car Onboard version uses the -COMM ERIC model that has the 14-pin connector.

The 14-pin connector exposes the interlock relay normally available on the C3 terminal of the regular IC650 charger.

The 10kΩ is really only needed if you are bringing the interlock line down (to limit the current), but you can just use the relay to disconnect the pin and not worry about the 10kΩ resistor.

I am guessing that Club Car also crippled that external model's ability to initiate a new charging cycle with AC disconnect.

If you want to use that external ERIC model onboard and have interlock control, your best option will be a small 120v relay to disconnect the interlock and connect the charger to pack positive when you plug the charger to the AC power.

The 120v relay connections would be:
COM Terminal = Pack positive.
N.O. Terminal = Charger positive output.
N.C. Terminal = Directly to Controller pin #5 (wire cut at Controller 16-pin connector to eliminate the 10kΩ resistor).
You can order the relay from mouser:
https://www.mouser.com/ProductDetail...AENZrAmmiTg%3D
The relay 120v coil (no diode) gets connected in parallel with the charger 120v AC input.

When you plug the cart to AC power, the relay closes which removes B+ from the interlock and connects the charger output to the pack positive terminal.

I know this is a loaded question, but would I be better Off just SELLING the ERIC Charger and putting a Lester Summit 1050 ON Board? If I'm tracking correctly, I can use the Lester Summit without making those changes, right? I just simply make sure the Lester Summit is setup for ON Board use on the App and wire it into the batteries accordingly.

The summit 1050W when configured for onboard will charge the cart fine, but the interlock will not work as default.

You have options on what to do, but the easiest will be to run the 2 interlock wires from the Summit II to the controller 16-pin connector.

Cut the blue wire that goes into pin #5 and wire each wire to one of the wires from the Summit II.

That way when AC is not connected to the charger, the charger interlock N.C. contacts are closed and the Controller works.

When you plug the charger to AC, the interlock N.C. relay opens and the controller goes into lockout.

OK, Thank you Sergio and FairTax4Me! I will give that a try.
