I also unplugged the shore power connection to make sure there wasn’t any power applied to the Southwind. I remove the cables from the chassis and the coach batteries. The radio gets powered from the chassis battery anytime its turned on, so it could have run the battery down in a few days. QUESTION: Why did the Chassis battery go dead in just a couple daysĪNSWER: I think I had the radio turned on, but the volume was low. I don’t need the Trik-L-Start module after all. This allows the the coach to charge the chassis and vice -versa. This BCC energizes the isolator solenoid when it sees either the coach or the chassis battery above 13.2 volts. I have a RV Custom Products circuit board, P/N CB-115 REV B. I did a lot of hunting and research on the BCC to find out exactly how it works. QUESTION: Why is the solenoid staying energized? This is why I didn’t hear it CLUNK when I pressed the EMER START switch, because it was already energized.ĪNSWER: This is normal. I then check the voltage on the battery terminals, no change, chassis = 0 and the coach = 13.2.ĬONCLUSION – The Solenoid is obviously bad, Even though the coil is energized with a distinct CLUNK, the internal contacts are not being made. I re-connect the coil wire, CLICK, it re-energizes. To verify, I remove the coil wire, CLICK, I hear it de-energize. I checked the voltage at the coil terminal and I seen 12.5 volts. I noticed the solenoid was hot, so I figured it had been energized for a while. I removed the cover from the BCC and measured the voltage on both sides of the isolator solenoid, voltages on the solenoid were the same as the batteries, chassis = 0 (zero), coach = 13.2.

I’m plugged into shore power so the converter is supplying the 13.3 volts and keeping a slight charge on the coach batteries. I checked the voltage at the batteries, chassis = 0 (zero), coach = 13.3. I then press the CONNECT switches, both solenoids click. I pressed the battery disconnect switches, I heard both solenoids disconnect. I pressed the EMER START button, nothing, no click, no nothing. I started the Southwind a week ago, so the battery should NOT have died in that short period of time. it did the exact same thing: Nothing, dead, no instrument lights, nada, zip…. The Southwind’s BCC should keep the chassis battery charged when its on shore power.Ī couple days ago, I was working on something inside and needed to start the engine. I ordered a Trik-L-Start charge module to keep the chassis battery charged when its plugged in. QUESTION – Why didn’t the isolator solenoid pull in when I pressed the EMER START button? Although I asked this question, I never investigated to find the answer, more on this later. HUM, the battery was 5 years old, the previous owner mentioned a couple problems, its probably a bad cell. I did a quick check with a voltmeter and the chassis battery showed something like 7 volts. I pressed the EMER START button, nothing. A couple months later, I went to start it, nothing, dead. When we first bought the Southwind, the previous owner said he had a problem with the chassis battery going dead. A little history first to explain the problem.
