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...

      The Rum has been dropping in flow and water level since the 20th from St Francis down if that helps

      Fishing awful this morning. Launched at 8:30. By 12:30 had exactly two small pike. Finally found some walleyes and ended up with 22 fish - NO BASS! bummer. Water cold - only 61-64 degrees. Weather man blew it again. Walleyes in about 20 FOW, best lure Lunker City Fin-S-Fish.   New camera worked well but had troubles with new sonar/GPS. Think I got it fixed once home.   Here is today's video: June 26 video

      We took our annual trip to Rainy Lake in mid-June staying at Taylor's Cove along Bear's Pass.  My dad started going there back in the late 70's and now brings me and my son.  Every year provides great memories, new and old.  Anyhow, fishing was very good, particularly for bass and walleye. Water temps ranged from 62-72 degrees.  Most days were about 75 degrees, overcast and breezy.  Our biggest smallmouth was 22" and biggest walleye was 30".  In fact we boated ten walleye 25" or larger.  We caught pike up to 37".  We found walleyes in weedy bays around 6-10' deep.  Bass were in 5-8'.  Most of the fish were spitting up perch so I imagine that's what kept them shallow.  A few pics to share.  Wish I could be there more often...

      I live 10 min from cabelas and they have like 4 trolling motors on the floor.... dont like buying something i cant look at.

      You can't find one? How much do they cost? Try Cabela's for starters.All the I-Pilot and I-Pilot Link models have Spot-lock.   http://www.cabelas.com/browse.cmd?categoryId=734095080&CQ_search=terrova   https://www.minnkotamotors.com/Trolling-Motors/Freshwater-Bow-Mount/New-Terrova/

      Nice, I'll have to start fishing it more and learn it.

      You can find crappies and sunfish anywhere on the like around the pencil reeds and/or cabbage.  One of the best spots is right in front of the resort, but don't limit yourself there as there are plenty of spots all over the lake for pan fish.  The nice part is that you will probably also catch bass while going for pan fish.  Good luck and remember to give other fisherman plenty of room.  No reason to fish close to others.
