ezgo wont go
ok have a ezgo electric series model and it starting going real slow
then don't go anymore -- well almost i read all the its testing threads and this is what i know form B- to the white wire on the ITS has 1.5 volts when the micro switch closes (powers up the controller) then at full throttle i get 1.7 and then it will ease up to around 2 volts then sometimes just putting the volt meter on the white and the black wire on the controller will make it move a little but very slow. so my question is ITS? or something else PS i do believe that all the connections are good Molex connector has been removed PSS here is some history on the cart previous owner put 6 8 volt batteries in it and something smoked. i got it about a year or so later after he passed and his kids wanted to get rid of it. all i found wrong was the micro switch in the pedal box was bad and one of the micro switches on the FNR was bad. grand kids been riding it for 4 months and one of battery cables got loose i think cause it melted the post on one of the batteries. after fixing that it ran good for about 3 days and then moved real slow. then does not move at all. thanks for all yo help |

Re: ezgo wont go
First think I'd check was the battery...put voltmeter across battery ,,,then see what happens to the voltage when you press the pedal

Re: ezgo wont go
Pack voltage stays the same about 38 volts before and after the pedal is mashed.
this was measured at the controller. oh one other test that i Did was measure across the white and black wire of the ITS or plugs 2 and 3 at the controller and that voltage is about 6 but it move around a good bit. 12 volts means the ITS is bad 14 volts means a broke wire from the its this is straight from Scotty B's page "DCS and Series carts have a signal range of 0.4-0.6v through 1.5-1.7v" but this one starts at 1.5 and goes to 1.7 and then eases up to two after about 3 or 4 seconds. so the ITS is either doing the wrong thing or the controller is outputing the wrong voltage guess i will order an its and see what happens |

Re: EZGO won't move, solenoid clicks, pack voltage 38.8
after performing some more test that I read on here, I am still a little confused as to what the problem might be.
EZGO series model 36 volt stock controller test that i have performed pack voltage 38.8~ before and after the pedal is pushed b- to b+ on the controller is 34.5 before the pedal is pushed, pack voltage when pushed. b- to m- 34.5~ before and pack voltage after the pedal is engaged thru wide open b+ to m- is 0.00 before and after the pedal is engaged thru wide open b- to white wire on controller (spade lug 3) 0.0 then- 1.3~ when micro switch is closed then 1.7~ when the pedal is all the way down (wide open) b- to black wire on controller (spade lug 2) 0.26 then 3.5~ when micro switch is closed then 5.0v~ when wide open white wire to black wire on the controller 0.26 to 4.0v~ when the controller is powered up to 5-6 volts wide open ohm resistance across the ITS 1.8 meg ( i know that this is a bogus test but why not) conclusion is either the ITS or the controller or both are bad. hate to thro parts at a problem but i guess i will try the ITS first and go from there thanks Ken |
