99 ez go with no power at key switch.

del50man · 08-30-2020, 10:55 AM

I have a 99 ez go that does not have any power at the key switch. I checked the wiring and the wire is fine. The blue wire at the micro switch reads .03v and the red wire reads .0 with key switch off.
With key switch on blue reads .057 and the red reads .0.

Any other test which I can check to see if it’s just the micro switch or possible test the fnr? All battery wires are reading 35v. I know it needs a charge to get 38v. I also don’t have a reverse buzzer going off.

The voltage going to the keyswitch starts with the reed switch in the charging receptacle and goes through MS-2 on the F/R switch assembly.

Schematic with solenoid activation circuit highlighted attached.

Ok so I tried to bypass the reed switch and still nothing happened. I did an ohm test on the wires as well and the wires are good. Is there a way to put a jumper wire to the Ms2. I checked the key switch and still no voltage there.

If you bypassed it at the charger port follow the black loom to the passenger side and look for a connection a few inches out of that loom in the red wire.

Yes I followed the red wire to the micro switch. I went ahead and hooked the reed switch back up since bypassing it didn’t work. The red wire goes to the micro switch where the key switch wire is attached to the other end.
The fnr has the voltage it should. But I’m sure the micro switches should be higher than .05 volts.

The path highlighted in red ought to have battery pack voltage (38.2V when fully charged) on it all the way to the solenoid coil.

Should there be any voltage on the fnr framing? I get20v
Also on the bolts holding the micro switches I get 12-20v

Ok that was a dumb question. Lol
So the outer part of Ms2 is getting voltage but not the same voltage at the top connectors.

You should be getting pack voltage on both sides of the Microswitch On the f/r when it is closed. Same is true for reed switch, key switch, and pedal switch. When all of them close, there should be pack voltage at the solenoid and it should “click” and engage.

I am getting voltage on both big bolts on the solenoid and none on the small positive side.
I get .05 ish when key switch is off on ms2 and nothing when key switch is on.
I get 12v at the reed switch when I disconnect the white wire coming from the reed switch that connects to the red wire headed to Ms 2
