how do I by-pass voltage sensor on total charge

FLMike · 10-09-2007, 02:11 PM

I have a '90 EZ-GO cart...the batteries are so depleted the charger won't come on to charge them. (I've checked the charger on another cart)

I've heard there is a way to go inside the Total Charge charger and change a wire so the charger will come on...

Anyone know what needs to change or have a wireing diagram for this?

Thanks...

DO THIS AT YOUR OWN RISK! RISK OF ELECTRIC SHOCK!!

Open up the charger and look for the relay. The relay is on the side of the pc board. There are 2 wires connected to the relay. One Black wire and a yellow wire. With the charger unplugged from the house outlet connect the 2 wires together. Now plug in the charger to the cart and then plug into the house and your set. The charger should be humming. If your not watching the charger it will boil your batteries dry so keep a close eye on it. About 10-12 hours they should be charged.

Not sure if all the chargers have yellow and black. All of the ones I have seen have a yellow and black wire going to the control board....I would strongly suggest charging enough to get the batts up enough for the auto to take over and get the charger put back together right.

Wow, Dooly what a quick response...thank you so much.

I will do exactly what you recommend, roady89....get the batteries semi- charged then reconnect correctly..

Thanks again!

i would highly recommend just charging the batteries in 12v series with a 12v battery charger for about 15 minutes per 12v set.. This usually gets enough surface charge to turn the charger on.

Or likewise if you follow dooley's instructions then you can just charge them for about an hour, then set it up normally again.
