Battery Boost Switch 3010

[rekwiat]

What position (up or down) to turn on battery boost? Newbe to MH.

If you are talking about the switch on the driver's seat base that ties the coach and chassis batteries together, the answer is neither. It is a momentary action switch and you need to hold it to tie the batteries together. Once released the switch returns to normal with the batteries separated. When you activate the switch you should hear the relay activate. If it does not click then check for the 5 amp control fuse in the panel at the coach door step well. Some units including mine, left the factory with the fuse not installed.

Normally the chassis battery (under the hood) and the coach battery (under the door steps) are not connected to each other. But if for some reason the chassis battery is dead (meaning you cannot start the engine) you can use the coach battery to provide power for starting the engine. There is a switch down low on the drivers seat (door side). When you hold that switch down, the coach battery is connected to the chassis battery. While holding the switch down, you start the engine, using power from the coach battery. In other words, it is like jumping your dead chassis battery from another battery.

As stated above, this is a momentary contact switch. Which means you need to hold it down the whole time you want the two batteries connected. Its location on the left side of the drivers seat makes it possible to hold it with your left hand while turning the key with your right hand to start the engine.

BTW, no need to do this for the reverse situation. If your coach battery is dead, just start the engine. It will provide power from the alternator to the coach battery.

ATVer, can you please provide more detail where the control fuse is? Thanks.

Thanks for the clarification. The dealer never told me about it.
