switched live....best place

[keith]

Hi

im looking to add a water pump to run my chargecooler....the pump will be mounted under the van...inboard/ parrallel to the sliding door area.

i want it to come on only when the ign is switched on.

could you tell me where the best, easiest , safest place is to take a live feed from......i then plan to wire a relay to draw 12v direct from the baterry.

as with most things technical......its a bit of a blurr.

( i have a few recommendations...ie fuel soleniod...but not really sure where that is....or if its the best.)

thanks in advance.
Keith

In the black box left hand side front of engine with the glow plug relay is a black wire or two. Connect to one of those.

Are they definately switched lives then.......

Now this isnt my knowledge, as i have none but i'm sure there is a thread on BY saying they attached to a connection on the alternator? From memory because it only becomes live with the engine running, as you wouldnt want it running with just the ignition on

Now that would be convenient.......looked but I can't find it on BY.....I don't want to start hacking into cables that connect to black magic things like ecu,s

Just pretend your pump is a fridge or leisure battery and follow the split charge diagram.

It's the thin blue wire on the alternator you need to trigger the relay btw.

go off the stop solenoid on top of the pump it should be the only wire to the pump that will start the chargecooler pump straight away when the ignition is turned

[keith]

Mine runs as soon as ignition is turned on and runs for a second or 2 after it is turned off.

That's the same black wire as the black wire in the black box.
