I have a 924G, the reserve beeper power supply reads 24 volts until I put it in reverse it drops to 0.7 volts. Is there a reverse switch relay? TIA
If you want an electrical schematic to go chasing power you will have to supply a Serial Number.
A quick look at a random 924G electrical schematic indicates to me that there should be no voltage at the reverse alarm until reverse is selected. At which point it should have 24v. Do the backup lights work.?
