|Cellnoid problem in coach||Paul||12-26-02|
|Problem with relay on cellnoid on a 2001 Challenger (Damon). Relay is used to convert the coach to 12v. There is no 12v power in coach and the relay keeps burning up from just the battery power. The coach is not plugged in, nor has it been run. What is causing the relay to burn? This being the 3rd relay. Thanks.|

|From the sounds of things, something is keeping the system in the 24 volt position. The fact you have no 12 volt power to the coach could mean that the plate that makes contact for 24 volts is burning to the posts and therfore not returning to the 12 volt position. You need to do a starter draw test before you put another switch on. Your starter could be overloading the system. |
There have been many arguements as to weather 24 volt is really needed for starting. This has been a long battle with the 24/12 systems. I have seen very many of these converted to straight 12 volts and never having a problem again. Most of the OTR trucks are now running 12 volt systems with 3 or 4 12 volt batteries.
