tow bar electric question powering fridge whilst driving

[sternal]

Currently have single electrics fitted was thinking today maybe I should fit the grey electric kit (12s) I won't be needing anything else on the plug apart from the fridge power (no battery in caravan )

Is it advisable to wire direct to the battery ? Id obviously need to disconnect if stop at services etc or is it better to wire so its ignition controlled ?

just trying to rack my brain as to what is ignition controlled in the engine bay ?!?!?

Advice gladly taken !

Wire to the battery via a (fused) split charge relay so it's only live when battery is charging.

You mean something like this ?

I assume instead of wiring to leisure battery it would be for the feed for the fridge ?

from the alternator which is the no charge wire (colour) ??????

[marlinowner]

Yes that would work, switched by the wire from the alternator. Or even simpler but a bit more cash-

and the earth wire coming from the fridge via the plug to the chassis ?

[marlinowner]

Yes

many thanks marlinowner

now all I need to know is what colour the alternator charge wire is ?

Will I need an inline fuse ? what rating ? going to the fridge ?

[marlinowner]

Blue wire on D+ alternator terminal

[marlinowner]

Fuse between battery and relay, size depends on fridge amps, maybe 20A?

brilliant stuff many thanks




so this fits the bill !

cheers sir !

That looks ok but be wary of using scotch locks, they can be unreliable.

It is handy having the permanently live pin 4 connected to the battery as a power source with a suitable plug and adapter for external things like air pumps, work lights etc.
