hlange Posted September 28, 2008 Posted September 28, 2008 OK, 1985 Venture Royale, 46,000 miles Battery level lcd always shows indication and red light flashes. I have tried the resister (1.1 and 2.2), taken the dash apart and checked all solder connections on the first board, cleand all connectors. Still shows indication. All other lcd indicators function properly. The only thing that I noticed on the board was that the solder for a black transister looked a little funky, all others looked good. I resoldered the connection to board joints anyways to ensure that thy were good. Ideas?
Neil86 Posted September 28, 2008 Posted September 28, 2008 Unhook the connector and test to see you are getting voltage from the resistor end.
hlange Posted October 2, 2008 Author Posted October 2, 2008 Tested the wire without the resister from the battery to the dash connection and it appears good (0 omhs). Rechecked the resister setup and it still shows the battery icon and the warning light. All other functions work.
mbrood Posted October 2, 2008 Posted October 2, 2008 If someone put 12v direct to the CMS from the battery probe line, they probably blew the IC in the CMS but it's available and can be changed... the chip is a TD62504P There are two on the computer board The battery sensor connects to pin 1 on one of the chips. That is the one to change.
