I have a 1991/2 Sportscoach with 12v electrics.... I am trying to find a replacement for the main isolating relay to the electrics... (mine burnt out last autmmn in Germany when we had a short and fire from the alternator circuit. It was "bridged" out to get me home to the UK by a local German garage,.... unfortunately I didn't check at the time and in the confusion the German garage kept the old unit, and now I don't know which to buy to replace it properly. I have tried a couple of heavy relays from trucks here in the UK, but they weren't continuous types, had too high a current draw on the coil, and overheated.
It's a continously rated coil, normally open, can-type relay, (I presume Delco because the rest of the electrics-alternator etc; are mainly Delco). The 'can' is about an inch and a half to 2 inches in diameter and about two and a half to 3 inches long. Coil is 12 volt. I don't know what the current rating for the contacts was/is,... but I've got a 120amp/hr alternator and 2 100amp/hr 12 volt batteries on the chassis. It is the main coil which is energised when you switch on the ignition, and which then energises all the vehicle electrical relays and circuit-breakers,etc.
Does this sound familiar to anyone?
Is there any chance that someone else knows what was fitted to a 1991 Sportscoach CrosscountryIV-RD 'pusher' (rear Cummins) running on a Spartan chassis?
I have emailed to Coachmen previously (I understood they had taken over the Sportcoach brand) but they didn't respond or answer.
Any hints/advice are welcome as I am a bit nervous about running without the proper factory specified electrics in place.
Even better would be if someone knows where I can order one from online.
Many Thanks for all replies,
