Habitation Wiring
Habitation Wiring Diagram Daisy's habitation wiring is essentially four largely separate circuits. The simplest is a transformer located on the bulkhead behind the battery and connected to the hook-up 240v. Charge is supplied to the battery via a diode which ensures there is no loss of charge across the transformer when the hook up supply is not connected. The transformer has its own built-in fuse. The second circuit comprises a lead from the vehicle ignition (A14) which closes a relay (R1) to complete a circuit between the vehicle and leisure battery when the ignition is on. This lets the alternator charge the leisure battery when in motion. More modern vehicles have technology to reduce the alternator current if the vehicle battery is fully charged so that fuel is saved. This then needs a more sophisticated circuit. Daisy does not need this complexity. Diode D1 has been added because otherwise the starter motor circuit takes power from both batteries. This can be...
Thanks for the info on fridge removal. Looks like fun. I'm currently trying to de-bug my LPG solenoid which isn't actuating, it's getting power at the panel, but the 2nd switch (I guess it's a 2 coil unit) isn't doing anything. I've already contacted Truma that made the solenoid and panel switch. I've got a feeling I may be replacing it with a 2 wire 12v on/off solenoid if the OEM is extinct at 25 years old. Let me know if you've dealt with this.
ReplyDeletebtw, I have a JB500 Van Tech book in Japanese that I'm trying to both translate using Google, and I've got some Japanese folks working on it as well. About half of it is easy to just figure out, the other parts are good to decipher, such as that's how I found there is a 2 - AA battery holder in the heater for the Piezo. Things like that.
I'd post the book here, but I can't see how to attach, it's less then 2mb.

DeleteI haven't looked at the gas valve but it must be in the gas tank cupboard. Email me direct and I will test mine too.
Nice Blog.. Have a look if you need any services..
