darthdicky Posted April 18, 2020 Share Posted April 18, 2020 I believe this is used to isolate my winches and whilst it works at the moment I don't like the rusty look of the terminals so I'm trying to work out what exactly it is? Can't seem to find anything quite like it anywhere. Is this sort of thing a more modern equivalent? https://www.devon4x4.com/albright-su280-isolator-250a.html Quote Link to comment Share on other sites More sharing options...
western Posted April 18, 2020 Share Posted April 18, 2020 I use a Thompson solenoid to operate the winch https://fourby.co.uk/500A-Winch-Solenio & one of these to isolate the 12v power, fitted in front face of the battery box, the key can be reached from my drivers seat. https://www.12voltplanet.co.uk/heavy-duty-tir-battery-isolator-switch-with-removable-key-250a-24v-max.html that Albright isolator would do the job.

Arjan Posted April 19, 2020 Share Posted April 19, 2020 We use the well know quality red keys to isolate the winch. Less money than another solenoid. Never a problem. Quote Link to comment Share on other sites More sharing options...
Escape Posted April 19, 2020 Share Posted April 19, 2020 It looks like just a big relay (solenoid), so could be used to isolate the winch or battery. But as above I prefer a manual switch, less electrics to go wrong. Not always easy to fit a manual switch withing reach, depending on where the battery is. You don't want big cables running all around the vehicle either. Filip Quote Link to comment Share on other sites More sharing options...
darthdicky Posted April 25, 2020 Author Share Posted April 25, 2020 Sorry, I should have said that this is a secondary isolator as there is a big manual isolator as well, like the one Ralph links to. I think the idea behind this one is to have a switch that has to be on to enable the winch buttons to work, which makes sense as I have knocked the switches in the past. If an Albright or Thompson solonoid can be used then I'll probably get one of those to swap over at some point as this isn't looking too great.

Escape Posted April 25, 2020 Share Posted April 25, 2020 In that case, wouldn't it be easier to put a switch in the feed to the control buttons? Less items in the 12V feed to the winch means less chance of resistance losses. Filip Quote Link to comment Share on other sites More sharing options...
Nonimouse Posted April 28, 2020 Share Posted April 28, 2020 Rich One 'cut off switch' minimum of 500 amp, use marine cut off switches, they are well priced, or the big version of Ralph's. Things will most likely go 'FUBAR' when the winch is close to stall , so pulling max amps One solenoid to operate the winch - the Thomson unit is brilliant, worlds ahead of an Albright and sensible money Quote Link to comment Share on other sites More sharing options...
