1990 DS - No power in reverse
My 1990 DS just started severely lacking power in reverse. If you are sitting on flat ground, it will ease backwards but will not backup any slope no matter the grade. Going to check the v-glide contacts this weekend. Anything else I should check?

Re: 1990 DS - No power in reverse
Welcome to BGW
This cart had a factory 1/2 power reverse. Verify this by the existence of a battery cable from the bottom of the F&R switch to the middle of the battery pack... It may have been removed and modified but if not, your cart runs on just 3 batteries in reverse. If one of these 3 batteries (drivers side) goes bad then the cart will really loose power in reverse..... Of course a bad connection or cable could give similar results. Can you post voltage readings for each of your 6 batteries? |

Re: 1990 DS - No power in reverse
Not that it means anything but the batteries are only 1 1/2 years old. I'll check them tonight. I know the connections should be right because the guy that installed the batteries at Battery Source said he moved the reverse cable back to the appropriate connection. Evidently the guy before me had it configured for all 6 batteries in reverse. Thanks scottyb.

Checked all 6 batteries. Not fully charged (wife took it to end of street before I got home) they range from 7.06 - 7.12. That's good, right?

Re: 1990 DS - No power in reverse
How many water holes in each battery ?
7v is high for a 6v (3 water holes) and low for an 8v (4 water holes) |

Re: 1990 DS - No power in reverse
If those readings were taken after the cart ran down the block and back somethings not right - maybe the tester needs a new battery? or the charger is 48v?
Can you check them again? Maybe change the 9v battery in the DMM ? |

Re: 1990 DS - No power in reverse
One time I was using a DVM and it was saying 4v coming out of a 110v outlet. Changed the 9v battery and it read 110v. These things can give some wacky readings when the batteries are low.
