Got a voltmeter on my 94 EZGO that won't turn over heres what I got !

This is like pulling teeth.
You are losing voltage somewhere. I am trying to determine where.

I want to eliminate the battery as a possibility first, and then go from there.

It could be bad cable connections at the battery, frame, solenoid, or selector switch.
I could be a bad selector switch.
It could be a bad solenoid.
We need to eliminate the battery first. What voltage are you getting from the load test?

Sorry cart around, I am at work and won't get to fiddle with it till tomm. Thanks for your input and please check back tomm. and I will have the info for you. Thanks to all.

Okay, did the load test on battery. When I press the pedal I still get 12.7 at the battery terminals.

Just to add this, when I run a jumper from the big positive side of solenoid to the little terminal next to the big negative terminal the solenoid clicks. Running the jumper to any other does nothing. Anything?

Come on guys, don't leave me now.

Verify you have the correct wires feeding the field side of solenoid.
No voltage present at field coil when key is off.
Voltage appears only when switch is on and pedal is pressed. Verify it is at + side field not neg wire. If you have voltage at both sides then you have a bad ground wire or wired incorrectly going to the solenoid.
Run a jumper from the + battery to + field solenoid does it click and start turning over engine? If it buzzes or clicks repeatedly
Go from - battery to - field coil and crank it.

Definitely check everything that my1423 posted, it is eliminating each end of each cable at a time.

Also remember this, you basically have no voltage drop. The signal isn't getting through.

You changed the solenoid, and it worked for a while. The problem is probably in one of the wires that you disturbed while changing the solenoid.

My experience is that the positive battery cable is the one that corrodes first. Check that one real good.

One more thing. This is a 94. I assumed that it is a 4 stroke engine. Is it?

Yes sir a Robbins 295 I believe. Thank you so much for all the info. Got to work a double tomm. But, should be able to post results Friday. Thanks for all the excellent info guys.

Okay, back now after work and Mothers day. I took battery to local auto parts store and they said it checked out okay. So now here is what I got:

Neg. battery terminal to pos. battery terminal 12.7 volts
cranking 12.7

Neg. battery term. to big Pos. term. on solenoid 12.7
cranking 12.7 to 13.0

neg. battery term. to little term on solenoid next to big pos. term 0 volts
cranking 9.2 volts

neg. battery term. to little term on solenoid next to big neg. term on solenoid 0 volts
cranking 12.0 volts

neg. battery term to big neg. terminal on solenoid 0 volts
cranking 8.8 volts to 9.1

neg. battery term. to selector switch 12.7
cranking 12.7

Neg. battery term. to both terminals on ignition switch (key on) both read 12.7 volts Cranking both read 12.7 volts (key Off) Only one reads 12.7

neg. battery term. to microswitch top 0 volts
cranking 12.1 volts

neg. battery terminal to bottom microswitch 0 volts
cranking 12 volts

OKAY now this is weird, 2 days ago If I ran a jumper from my pos. battery term to the little term. on solenoid next to big neg term, nothing
jumper from pos battery term to starter nothing.

BUT! while taking these reads, I noticed my cart stop clicking when I was pressing the pedal. Then I noticed that I am NOW basically getting 0 volts at any spot I was before. Nothing past the solenoid, I get 12.7 at the big positive term on solenoid and nothing no where else cranking or not. BUT when I take my jumper now and go from Posit. on battery to little term. on solenoid it turned over, then when I ran my jumper from the posit. on battery to starter gen. terminal it turned over. Now it has stopped, and I get no reads past the solenoid cranking or not and now the jumper does not work in either spot but it does make solenoid click when I hit it from the positive terminal to the little on solenoid. I am lost. Any ideas, I went in to this today thinking my starter may be bad what do you think?

[Mobug]

Just thinking, if the starter gen. is good, shouldn't it turn over every time I jump it from positive terminal of battery to starter term. on starter?
