Greetings from Seattle. First time post.

Installed a T-Max dual battery system. Seems to be working perfectly however the solenoid gets very hot to the touch. Is that normal? I used their supplies wire so kept it to spec. Here are pics.

Looks like a nice bit of kit - can't think why is should run hot if properly installed but clearly others have had the same problem as you:

Thinking of doing this myself so would be interested in your findings

This guy says its normal and fine:

Im no expert but if its to hot theres got to be an issue, most likely the relay isnt man enough for the job.
I also notice your gold battery clamp appears to be to big for the battery terminal (can see a gap on the right side) and the bolt end has bottomed out.
I think G stuart had one burn out/fail when pretty new.

hi

indeed @lynall i had a faulty solenoid from the beginning, was replaced under warranty , however it wasn’t hot , it wouldn’t switch over when i pressed the link button inside the vehicle

@AdaminIssaquah

have enclosed some pictures of my install

my solenoid has never got hot,

1) how have u run ur earths please
2) have u tested the solonoid to ensure its disconnecting with a multimeter and the internal relay isn’t fused and therefore causing the heat ??
3) have u installed inline fuses
4) is ur aux battery fully charged and what type is it

plse feel free to u ask any questions , plenty of us here happy to help

can u take some more pics please , just showing more of the full install , ie how and where the wires are connected etc , thks

assume ur going to recrimp the wires , ie exposed wires, along with proper heatshrink and sleeving, etc

also agree that brass battery post connector looks too big, otherwise ur asking for trouble, especially when it comes to wiring

PS, if i may say , we normally pop into the introduce section , lol

just looking at that , blue wire should go directly to the positive side of the battery terminal and not to the solonoid
