I recently added a second battery to the back of my bakkie and wanted to install a solenoid in line to prevent my main battery from running down when the car is not driving.
I first installed a solenoid and it got very hot after a few minutes. I was then told that its because the solenoid is not rated for continous use.
I then replaced it this with a proper cole hersee solenoid at a significant more costs. But now after ten minutes or so it also seem to be getting hot. Is this normal? Should i be worried about this?
Does anybody elses gets hot? I was told this was the same solenoid as in the national luna system without the gauges and timer etc. does the NL one gets hot??
I am leaving for a 2 hour trip or so tomorrow and am worried whether i should just remove the solenoid again and just cut my losses and revert back to unplugging the cable every time i stop??
Any help/ suggestions will be appreciated.
The solenoid I have now installed...

They do get hot.

The coil circuit (control circuit) in a continuous duty solenoid is usually energized for long periods of time. Under these conditions the coil will generate heat and within less than an hour the solenoid housing will become hot to the touch. This is normal. Always make sure that all wiring is properly sized for the load it is carrying, that the terminals are the correct size and have been securely crimped to the wire, that the terminals have the proper torque to the solenoid studs.

Mmmmm just wondering if the previous one was not the right one in any event...
RTFM (read the flippen manual) I guess.
Its amazing how other people seem to get this info effortlessly and google does not seem to be my friend. Hence this great forum.
