07 Sun Voyager Coach Battery issues
Hello all,
I am new to the forum and new to owing a class A. So I recently bought a 2007 Gulfstream Sun Voyager model 8389 and I am having some problems:
If engine is running and the generator is started the dash lights up and an audible alert indicating a battery system problem. Then the generator shuts off. Here is some things I have done with no success. I purchased two new deep cycle marine batteries and installed in parallel I measured the chassis battery at 12.6 volt with engine off and 14.3 running so it seems alternator is fine. The new coach batteries are not charging via the alternator and slowly dying as I start the generator or use batt power. I have to use an external batt charger to re-charge the coach batteries. There is a error code “29” on the Owen Marquis Gold 5500 indicating high battery voltage. With the engine off the generator works some times but other times it shuts off fairly quickly and inside the coach I hear a click like a switch. I located the automatic transfer switch (it looks fine) and when plugged into shore power I have 120 voltage (I did not check the voltage for the generator wires)I bought this from someone that absolutely knew nothing about RV’s but that’s about where I am too so it was the blind leading the blind. I have a few other issues but this is the most important one I need to address. As for shore power I can only hook up to a home 20amp service. But found this also fails in charging the new coach batteries. I have checked literally all the fuses I can find and they are good. I’m not sure if when I installed new Coach batteries if something shorted but I don’t see a high amp fuse near the batteries to check. I’m not sure if this could be a solenoid or?? And if so which one? Any help would be greatly appreciated. Thank you
Brad
