Smile Re: Relay Wiring Help -- Diode Needed?

Every once in a while the LED lights will be so low in resistance that even the flashers that are designed to work with LED lights still will not flash. The lowest resistance flasher is called a "no load" flasher. I have even had to use resistors on each line to fool the flasher to work. Superbrightled.com has the resistors in stock.

The reason for "all negatives" terminating on Controller B- is so that the OBC can measure any current being used by the DC converter and accessories.

If You have an "isolated" type converter, and that would be specifically mentioned in the instructions for the converter, then the 12v negative output of the converter would be the only negative source for the 12v negative block.

Even on this case, the negative source for the 48v side would still have to be Controller B-.

Moving the ground and replacing all the diodes corrected the circuit design you helped me with. I can control the lights independently, the tail ights / switch LEDs work with the relay AGAIN.

Using the B- connection appears to make the OBD control the output voltage at exactly 48 volts, vs current pack voltage reflecting charge level. I'll have to rewire my voltage meter directly to the pack to fix but that is easy in comparison.

I checked continuity on all the wires for the turn signals, which all checked out from the assembly to the wires in the dash. Replaced the flasher module with an advance auto one I picked up yesterday and works with my factory lamps. Will not work with my LED mirrors. I have a deluxe signal assembly coming tomorrow which will allow me to re-add the horn / H/L switch that used to be at my feet. Hoping it comes with a flasher that will work with the mirrors -- they better made by the same vedor (RHOX).

Theonly problem I see now is when the headlights or LED bar is on, the turn signals stop working?

THANKS again for all your input.

Before I nuked the flasher module I got from club car (a bit pricey!) they were working so I assume I don't have to have anything terribly odd to make them work. This cheapo I got won't power them - hoping the turn signal assembly has the correct one - if not I will check out the link above.

UPDATE -- Bad grounds on the tail lights were causing the flashers to not work with the headlights/taillights on.

I knew I should have just bought the LED kit, I spent 3 days or more mucking around with crusty old corroded wire issues.

LED mirrors are also working with the replacement flasher so no need for resistors!
