We are getting close to completing this project.
I 'm guessing that the multi meter can serve as a charge level indicator for the 36 volt battery pack. Fully charged, the meter reads 38.4 across the spade terminals on the relay. It reads 39.1 across the batteries terminal posts. Is that difference to be expected?
After running the car, what reading would indicate that it needs to be recharged? If the reading falls below 36 volts, will the car still operate?
Is the analog golf cart charge meter providing the same information as the digital multi meter?
I'd like to add a secret kill switch for security. Would interrupting the positive wire on the forward side spade terminal of the relay be a good plan?
Our project is complete and we have you to thank. It turned out better than I imagined it could and we could not have done it without your help, so THANKS!
I put a switch in the black ground wire going to the relay, but in either switch position, the original on/off switch still lit up the indicator light and the charge meter. I took the switch out and reconnected the ground wire which has the green shrink tube. It did not occur to me to try the throttle to see if the kill switch was effective in keeping the car from moving even though the indicator light and meter were getting power.
