Troubleshooting question

[Durney]

I guess I mispoke about the "series".

Walter, I have a DS. Is the test the same for the controller?

Fan4 - Yeah I just cant stomach the idea of having 750.00 in 6 8v batteies for the conversion so hopefully when I do some more testing if it is one battery I can just replace that one. They are a generic black battery but I was told when I bought them they were "US Battery". I sould have just bought Trojans at the time.

Test results. (Done with solenoid NOT jumped)

Both small terminals - .5v resting 55.9v pedaled
Blue wire closest to red main and batt grd. - 56v resting and 57v pedaled
Blue / White closest to yellow main - 56v resting 0.01 pedaled
Jumpered green / blue at mcor runs then stops (same)
Checked each batt at run and none drop below 12.5
When acting up i checked voltage at solenoid smalls 55.9
If i let it sit for a couple minutes and then throttle it, (on stands) it runs and i can modulate the 4 speeds but as soon as i lightly load it with the brake it shuts down

Frustrating....

By the way I assume this has some sort of differential (watching only one tire getting fully driven

That is NOT a US battery I can assure you.....

So if you probe only the 2 small terminals with the cart in Run, key on, and Go Pedal slightly depressed, what do you get? And if the cart quits, can you get the same voltage??

[Durney]

56v across smalls and if i switch the probes 36v (KO,run,pedal)

You red should be on the one with the light blue wire and the black should be on the one with the blue/white wire.

Durney, All of those voltages looks good. Now do the check Nole suggested and see if the stay or go away when it quits.

[NoleFan4Ever]

Yes, and then we will back trace it....

[WalterM6]

What kind of voltage do you measure across the big terminals on the solenoid? In standby and run.

[Durney]

56v on smalls (connected per you) and yes it drops out when it fails. Same with large terminals.

On stands it seems to run right up to speed until I put a load on with the brake, then it shuts down.
