self switching relay

[birchyman]

if you have a smart relay that doesnt switch on and off ,or chatters ,there is a trim switch on the circuit board so you can set them because of different voltages in old busses they might need a tweek but wired with correct cable you can get them spot on

I bought a 'Smartcom' self switching relay for my leisure battery... It lasted a whole of 5 minutes!! Back to the oldskool standard relay now and can't fault it.

I had a self switching relay and i had all the symptons you described but i'm sure my relay was a solid box with no way of adjusting it so i also went back to old school tecnhonlogy and fitted a 40A relay.
No issues with it since

if a relay breaks send it back, i fit hundreds of these to cars every year
to be honest i dont need comebacks and because they are fitted "inside and dry" they are the most reliable i dont know which one you used froggy but ive fitted most and they all are adjustable some have a smal hole under a sticker

The one i had came from a caravan shop near me, cant remember the make. To be honest if i had known it was adjustable then i would still have it fitted but the constant chattering when we were camping drove me nuts and as i had a 40A relay in the garage it was just as easy to re-wire.

This was the relay i had fitted, someone on here now has it (sorry i cant remember your name )

what are these 'smart/self switching' relays for? to isolate the leisure battery from charging circuit if the engine isn't running?

 

[james_stan]

Pretty much.

Though it also helps to direct the cahrge to the primary battery first, so
only when there is a low electrical load on the main system and the regulator
output voltage rises will it switch the relay over to charge the leisure section.

Cheers
