Hello everyone,
My Mh was not cranking so today i removed the batteries and got it checked. Both batteries came out good with 13.47V. What do i check next to start the Mh. This is first time happening so please pardon me if i ask some basic questions. Thanks very much for the suggestions.

Is there a chassis battery disconnect switch, I'm sure there is, check that.

I don't know if there is chassis disconnect. I have a switch for house battery disconnect.

Take a look at the manual, I'm not familiar with your coach but I have replaced my battery disconnect switch twice & that's exactly what happens when one goes bad.

I've had loose connections at the ignition switch that caused a no start situation. When this occurred, I could start the engine with a screwdriver at the starter connections.
I tightened the connections at the ignition switch, reinstalled, and no problems since.

Thanks guys. Will look into it as weather permits and keep you posted.

Do you get any lights or buzzers when you turn the key?

Mahakal · 03-05-2014, 03:01 PM

No buzzer and lights. Backup camera start.

Hi Mahakal,
1. If you have a chassis battery disconnect switch it will be in the engine compartment.
2. When the batteries were tested, was a load test done?
3. If the above are okay, take a VDC reading at the starter. You'll need an assistant to turn the ignition key to the start position when the reading is taken. If no VDC then you'll need to determine if the start relay and or any fuses in the start circuit are bad.

Hi
The battery tested good. Both at 13.47v. What does vdc mean. Sorry not too familiar with the acronym.

Is there any power at all to the dash panel?

We had an issue with ours where the entire dash panel was dead. It turned out the leveler tripped the engine breaker. The yellow rotating lever of that breaker is just visible through the rear engine cover on our DADP. Once I reset that breaker, the power to the dash was restored.

I also have a 2002 KSDP and the previous owner had a similiar problem and it turned out to be a 150 amp fuse located on the frame rails by the engine I believe that is where it was located.

Had exact same, turned out to be a loose wire near starter. Turn the key on then check the voltage at the engine kill switch if you have one. Should be 12v with the kill switch on or off. If you measure something like 3v or so with the kill switch in the on position, you have the same problem. Easy fix.

Hi Mahakal,
VDC is "volts DC". The question about the batteries being load tested has not been answered. A load test is just as or more important than the state of charge.
