Crown WAV50-84:
Will not show full charge

Hello,

So we have charged this wave several times until it shows green. We even load tested the batteries and we know that the batteries are good, but the BPI still only shows the flashing battery light and the wave is behaving as if it's almost out of juice. Any advice on how to fix this?? Thanks

Hello, will This work with a RC3020? Everything works except it will not go up or down. The battery voltage is reading 34 or 35.
Dash battery has one red bar. I'm pulling my hair out. Any help is appreciated.

You need a 24v relay, the coil fed from terminal board TB201-2 which had wire 2935 red/white wire they are numbered, and -Ve from lift pump terminal green wires attached, then the switched terminals +Ve from ED contractor which has red wires attatched, and other side the wire 2935, which goes to the bdi. So you are switching straight battery volts to bdi from ED contractor

@southernviking, can you tell me what i need exactly to get it done. I have a wave lift that is having this issue. What relay terminal do i need? Where is the 2905 red/white wire , white wire located. -VE = meaning? i would like to bypass the wire to the bdi but not sure where to start. Thanks

The problem is the batteries are a little old, and the voltage drop through all the switches etc before it gets to the Bdi, you can trick the bdi by charging momentarily so the charger pumps voltage in the batteries and raises the overall voltage but you disconnect before it's finished charging or drive it for 5 mins to lower voltage then charge it because it will say it's charged and stop charging, I am a crown tech, and we fit a relay at terminal board that bypasses batt voltage straight to bdi I think wire 2905 red white wire and a white wire on the board, -Ve on pump to coil, main relay voyage through relay to white wire on the board, this sends voltage straight to. Bdi

Sounds like loose or bad connection problem. Voltage starts at line contactor by the batteries then goes to the front flip down were it goes through the fuse, emergency disconnect, drive tow switch and connections then through the mast cable to key switch and back down mast cable before being sampled at the controller for battery state of charge. So all you can do is clean and tighten all connections while checking to see how much voltage drop you have.

The flashing light is the battery icon. Below it is the diamond icon with the question mark, which is showing that no one is on the wave with feet on pedals and hand on handles

Is it a flashing bar on far right side without battery icon being lit or is it left side flashing bar beside the battery icon?
