Guest isolator switch

11 posts in this topic

I've got an isolator switch between two batteries in my boat. Apparently it was installed incorrectly or it isn't working, because it's not isolating anything (current runs both ways between the batteries).

Where can I find the info I need to get it set up correctly? I Googled for "guest isolator switch", but can't find what I need.

Yes, there is a bunch. But what I need is an online manual to set up a Guest Isolator switch (or something that'll tell me how to do it). Where can I find that online?

Is what you have an isolator or just the orange battery switch that has positions for battery 1-2-both and off?

I am guessing that it is like any single pole double throw switch. You have a common that would go to the generator and two outputs, one goes to each battery that you want to charge. Take an ohm meter and you will have continuity across 2 terminals. Turn the switch to the other position and you will loose continuity between the two original terminals but you will have continuity between the third terminal and one of the two first terminals. That original terminal that has continuity between both terminals depending on switch position is common or generator. It is hard to type this so I hope it isn't clear as mud. Hope it helps.

I assume you've checked the Guest website? Guest is a sub-brand of Marinco.

I checked their website- didn't find anything helpful.

The one I have looks just like this:

I don't believe that is a switch. It is an isolator. There should be one terminal that goes to the generator and the others go to the batteries. There is a diode that prevents the reverse flow of electricty so that your starting battery does not draw down. The terminals must have some kind of markings. Don't guess there has to be some kind of identification.

I'd think one should be able to determine the correct connection by the terminal markings. Are there any markings by the terminals?

If all else fails, just call them and ask for help.

Scoot - I'd take an ohmmeter to determine the connection.. I'm completely guessing, but does the middle one connect to the alternator (or, in this case, a jumper from your starting battery to this isolator box) and one on the side to the other battery?

Since you only have two batteries I'm wondering if you need the two battery one... you pretty much have to connect the motor's battery cables to the battery, and then run a jumper from the battery to the isolator box alternator post.

Just a guess...

      Anyfish2 - thanks for the reports. I believe it was you who had written a little summary that included a rough estimation of when the LF river busts open and muddies the Rainy.    Can you (or anyone) comment on when that's looking likely to happen? anyone know when the river cleared the Frontier landing? I think you said that happening gives a 1-to-2 week notice on the LF breakup.

      recommendation for first timers to northern Minnesota?  we need decent lodging, boat or sitontop kayak, smallmouth is our favorite but we will fish for anything that will bite artificial.  thanks in advance for any help.

      My Alaska trip fell through, so I'm thinking having never been to Minnesota that should be my destination. thinking a week in august. Probably start International Falls or Duluth. We need a resort with sit on top kayaks or aluminum boats, comfortable lodging without being plush and not ripping our heads off pricewise.  We will target Smallmouth, but if it will hit a lure I will fish for it. any recommendations would be greatly appreciated.

      Went out of Stoney Point sunday morning.  FYI Watch for deer almost smoked a few on the 20 mph section coming back into the access!  There is an ice heave forming off of the rocks going straight north.  If you want to fish Paris Trench people were crossing instantly using boards.  We weren't gutsy/brave/stupid enough to cross there since we were pulling a trailer behind a four wheeler and had 3 of us with all our gear.  The ice was sketchy from access to point at the point the ice heave goes a little further away from shore and it allows you some room to avoid the point's tip.  There is open water immediately around the point tip but ice looks great if you follow the tracks and avoid huging the tip.  We couldn't find a place to cross the ice heave to get to Paris Trench so we were going to try a few spots further north since we could see a few groups set up north a ways.  About 5.5 miles north of the access the ice heave quits and you can cross it without any worries.  Since we could cross the GPS spot we wanted to fish was only 2.5 miles away and we fished there.  Out in the middle we had 26-28" of ice and barely made it through.  While fishing a plane landed on the lake and a 1/2 ton extended cab pickup came from the NE some where, it was too foggy misty to see where and we didn't see him leave.  Coming back from Stoney Point's Tip to the access was very sketchy.  Made me nervous since there was a lot of slush and water but ice held us up.  If you plan on going out next weekend you may need to find a different access, or atleast I would!  Talked to a guy who came in behind us, they crossed the ice heave at the access using boards how they did and they said it was very slow and only got two.
