Split charge relay

Post by D16LJM »

I have been playing about with the van today and have found the split charge relay to be fried, the relay on it is an old Halfords split charge for fridge and aux battery, I have looked in wiki but was wondering if someone can tell me if the relay in the below link is suitable.

Thanks Pete

Relay Fried! tells you that your existing unit was working hard and perhaps not up to the job. Was it an intelligent relay? (voltage sensing) or standard relay with Auxilary fridge take off?
IMO you would be much better off upgrading to something that can carry more current as 30 amps is VERY border line: LIKE:

Is your relay protected by fuses at both the starter and leisure battery ends?
If so, I would have hoped that the fuses would blow before the relay fried itself?

Trouble is: these 30amp relays are often protected by 30 amp fuses so they are working at or above their limit for a short time on initial start and as a consequence get hot/burnt out, over time.

Trigger is from the blue 'exciter' wire on the alternator.
