Default Re: Fully charge but no power

take a closer look at the foward reverse switch might need cleaning try electrical contack spray cleaner if you still have problem,s maybe your solonoid is old &worn out motor runs fine when wheel,s off ground cause there is no load on it ! you can jump solonoid out with screwdriver this operation take 2 persons one drivin &one in bag well if it still dosent work dissconnect m-minus on motor controller also remove cover on v-glide wiper &spray cleaner on throttel those copper wafer,s inside the box be gentle with it all part,s can get brittle after 15 yr,s at the shop i use muratic acid to clean switches then rinse with contack cleaner watch out the fumes will make ya gag!!!

Question Re: Fully charge but no power

Does it have a brush wiper pot box mounted on top of frame with linkage or is it a small black box under the frame at the foot go pedal.Ohms readings are different for the continuously varriable pot(one under frame)0-300ohms pedal
at rest,to 5500ohms at full throttle.A range at full pedal of not less 4600 ohms and no more than 7000.Dave

"dissconnect m-minus on motor controller" on the controller?

The POT is located above frame right behind the charger receptacle within the battery compartment. It is connected with a 6 square pin plug. I do not have a wiper switch. but will check to see if there is anything located by the throttle underneath.

Thanks

Tightened everything again. Took cart out of garage and depressed accelerator. Small shutter, creeps a little then it goes full speed. Similar results in reverse.

Does this sound like the POT

Thanks

I just want to make sure when you said 0 Ohms = OK
When U say 5.1 is that ohms or K-Ohms (5,100 Ohms) if it is K-ohms then
POT is working as designed for Min and MAX , and at mid point I would expect between 2,000 and 3,000 (2-3 K-ohms) If so then my guess is the
Controller is getting the correct signal , its just not passing the change to the motor. So the controller is bad !

If at mid point the cart is still < 1,000 Ohms I would say Pot is bad.

I rechecked the ohms on the POT this am.

readings are k=ohms

as I depressed peddle

1=0
2=.91
3=1.64
4=2.57
5=3.58
6=4.6
7=5.59

These readings are not exact to the test procedure doc you had me checkout. However it does progress from 0-5.59.

So are we back to a bad controller? And should I consider clean the contacts as suggested in a earlier post ?

Thanks
Judge

Adsolutely , bad controller !
Call your local shop and see if they can bench-test controller ,

While U are at it I would opt. for 400 amp or better controller and
upgrade all 6 gage wires to #4
then upgrade to High performance solinoid and watch this thing Fly .

Thanks to all , you have been very helpful. I spoke with the local shop and they say it can only be tested in the cart. Is that accurate?

Thanks

Smile Re: Fully charge but no power

Judge,we'll give this a try=controller input test,disconnect batts,disconnrct 6ga white cable from A2 of motor,tape up,reconnect batts,switch either F or R,depress go pedal,solenoid should close,and should be able to read batt voltage across small terminals of solenoid.
Put switch in F or R remove 18ga red wire from terminal 1 of comtroller(A on early contoller)VOM black to B- on controller and red to 18ga red wire,depress go pedal solenoid close,you should read batt voltage.
Controller out put=VOM red to B+ and black to M- should read 48v capacitor charge,key on,switch to F or R,depress go, with go pedal full down you should read full batt voltage.
On the first part of test the capacitor voltage:anything less then 48 volts the controller has a capacitor problem,mine passed input and output but capacitor voltage was 31v.bad contoller!!! hope this helps DAVE
