12v Battery Clip

[giw12]

Hi

Probably a dumb question, but I’m trying to connect a 12v battery clip (red and black croc clips at one end and cigarette lighter socket at the other) but no negative terminal under the bonnet.

Do I need to remove the battery cover and attach straight to the battery?

Assistance appreciated!

Any suitable bolt head in the engine bay will likely be at chassis potential and so will do as the -ve connection.

The socket in the boot area however is already permanent live and I would have thought this would be a better solution than messing around with croc clips??

Cheers

Hi
It’s for an electric pump which blew the cigarette lighter fuse. The instruction manual says that in this instance I should go for the croc clips option?

Just thinking......is it a viable option to use a higher rated fuse? Any other options?

no

No... thats not a good idea. Your best option by far is croc clip - positive to the terminal under the flap in the engine bay and negative to the chassis. you will find a collection of earthing bolts attached to the suspension turret a few inches to the right of the positive terminal.

Ah!

Yes, in that case (as already advised) - use the croc clips on the "under the bonnet connecting point" and a suitable chassis bolt head.

There ought to be a fuse in the (cig lighter) plug of your pump which should give you a guide of what current is likely to be pulled.

No, the fuse you blew should be replaced "like for like".

The 12V socket in the cargo hold is rated for 10A.

If you need more and you have the 13-pin tow electrics installed, Pin9 is permanent-live rated for 15A.

Here's a pic for under-bonnet connection. I use this for my SUP eletric pump.

That's for jump starting - for electrical loads you should connect the Ground crocodile clip to the chassis rather than the engine - but for a small pump the impact will be negligible.
