THOR BATTERY ISOLATOR RELAY AND DELAY HOW TO

It will lead to one of the terminals of the isolator.

If you don’t know what your alternator looks like, follow the big wire from the positive (+) terminal of your engine battery. It will lead to the center binding post of the isolator. If you have trouble finding the isolator follow the big electrical cable from the alternator. Location will vary from an obvious spot on the firewall to practically hidden under the engine battery. The isolator will be mounted under the hood, close to the alternator. We will assume you have lead-acid batteries (either AGM or wet cell), which have a fully charged resting voltage of about 12.7 volts.

Since our Class B has an isolator, we will describe how to find out if the isolator is the source of your charging problem. If you find you have a problem with either your house or vehicle battery getting charged, it is important to check your isolator or separator. Unlike an isolator, a separator will draw some current while idle. In addition to charging both batteries from the alternator, the battery separator allows both house and vehicle batteries to be charged when you are plugged into shore power. However this article will not discus how to test a separator although the process is similar. Shown at the right is a battery separator. The job of these devices is to charge both house battery and the engine battery, yet to keep the batteries separate or isolated from each other so you will not deplete your engine battery if you run your house battery too low (and vise versa). Alternator power flows normally through an isolator or a separator. Your alternator will charge both your engine battery and your house battery. The easiest and fastest way to charge your battery is to drive. If you camp without electrical hookups it is important that you keep your batteries in good condition and that they get charged. Battery Separatorīatteries are vital to RVers. Or you can spend a lot more on a more versatile multimeter. A basic multimeter from Harbor Freight can do what you need for $5.99. Your will need a multimeter (sometimes called a VOM or Volt Ohm Meter). It is important to be able to do some basic troubleshooting yourself to fix the problem. Note that even if you have two (or more) house batteries we will use the single term battery in this article. Nearly every motorhome owner will at sometime experience a charging problem with their house battery.
