Redarc

mines mounted horizontal, easier as that is where the bolt holes are and it stands vertical as it came in the box. I can only speculate as to why it states that it must be mounted on a horizontal plane, maybe something to do with the circuitry or internals?? Dunno. Perhaps you could make a bracket, L shaped that bolts onto your vertical plane, but allows the redarc to be mounted on a horizontal plane? Just a thought.

As for how hot, mine gets warm, and rightly so with all that currenty stuff that flows through it. They dont get "argh I cant feel my fingers" hot, but mine gets "hmmmm, that is warm and should let go now" hot.

I have had no problems at all with mine, Its great, easy to fit and wire, and then forget about it.

cheers

Try redarc themselves. They are well known for good after sales sevice.

Ours has always been mounted on a vertical surface in the Pajero and never had a problem, so far. It's been like that for 2 years now hope this helps.

Mines vertical too.

Hot? &*%#%$ I shouldn't have grabbed that %#$@%$#@$!!!!

This is how mine is mounted, made a bracket out of scrap beaten into shape and rivetted to the inner guard. It has been there two years and no problems so far. As for heat Redarc say

"QUESTION: My smart start gets very hot when operating. Is this normal?
ANSWER: Yes, it is normal for these products to run hot. A high current solenoid requires high power on the coil to ensure a good contact. This
results in heat dissipated in the coil body."

I prefer circuit boards to be horizontal. I have a theory (anecdotal) that components vibrate more if the board is vertical. I can only back it up with a couple of odd experiences where stuff failed when mounted vertical.

I fitted mine myself but didn't read the bit about horizontal, so mine is vertical.

Has done 10,000k with the trailer on and the trailer battery connected via Anderson plugs, and no problems. The 10,000 was to Cape York and back, so there was plenty of vibration for the Redarc to cope with!

Mental note - make an angle bracket and re-position it to vertical one rainy day....

The Redarc is a solenoid and has a moving plunger. Friction and gravity will case wear in a vertical mount position. The resulting filings and rough edges can cause the Redarc to bind or not operate freely.

Thanks for all the replies fellas. I installed it this arvy on a vertical surface in the engine bay close to the battery. It seems to be operating well so far. When I get some more time I will probably work out a bracket to mount it on a horizontal surface.
