Batteries say charged but nothing works

[OKJerry]

We've recently purchase a 1999 Cutter. The batteries were going down. We thought we had discover where a disk changer was trying to change disks even though there were no disks in it. I think the salesman left it on when we were looking at the RV.

For the last month it has not been a bother. This week the motor won't turn over and the step doesn't come out when the door is opened by the key.

The batteries say full charge.

We are at a loss as to the problem.

Jerry,

I know nothing about MOHO but thought I would post to move it back to the top of the page.

The only thing I coud say is check the battery terminals and make sure there is no corossion and they are TIGHT. My truck does that when the cable loosen.

Good luck

If there is no 12VDC present in your coach, you probably have a battery disconnect system that has a bad disconnect solenoid. If you have a switch either near the entry door, on the dash or in some other control panel that is labeled something like 'house batteries', 'store/use' or 'battery disconnect', then you have one of these devices.

They can be located anywhere in the coach, but are more than likely situated near the compartment that houses the house batteries. The disconnect solenoid looks like a can, usually black, 2-3" in diameter and 3-4" long with 2 heavy wires (battery leads) and 2 light wires (control wires) coming into it. It should be replaced with the same or similar unit.

You may also have an emergency battery connect switch at the drivers control panel on the left. You could try that as an alternative feed to see if you get power when the switch is operated (although the entry door switch may override that one)

Don't forget thestarter motor - and I think the steps - are supplied from the starter battery in the rear drivers side compartment NOT the house batteries. Maybe the engine batteries are flat in which case using the emergency connect switch might work.

Try touching the solenoids and see if one is hot.
If nothing else works, disconnect the battery cables, clean, and reinstall. If its the solenoid, it will usually work after cooling off with no power. If things now work, have someone activate the switch and you listen and feel which solenoid it is for furture reference.

Battery Drain/Headlight Relay Fix

"Battery drain may occur if the headlights are left in the high-beam position when the engine is shut down. This does not affect the operation of the headlights in either high- or low-beam position, but can drain the chassis batteries in four to five days if the vehicle is not operated.

The Signal source for the Hi/Lo dimmer control of the headlight relay needs to change from battery power (circuit 24) to ignition power (circuit 74) in the cab harness. This will eliminate battery drain, if the dimmer relay is left closed.

Since June 1999, a new harness has been installed in vehicles. There is no field action necessary for VCL models as none had been build as of the changeover date.

XC chassis build with System III multiplex wiring (pre-series units built May 1998 and production units build since January 1999) need to have the wiring modification.
This may be some of the problem?
