What battery are you using?

nearside engine bay is the place to go, I'd to do a bit of panel beating to get the clearance under the bonnet.

A tidy up, some paint and a bar to move the washer bottle forward.





And hey presto job done!

Thats exactly what i plan to do.

how have you hooked power up to the second battery?

Here's a copy of the reply I posted in another topic in this forum,
On the subject of alternators, I've fitted a second battery (Numax)in the engine bay and wired in parallel with the original though a 200A relay. The switch live to the relay is an ignition live (cigarette lighter) through a switch on the dash.
When I close the relay there's a notable extra load on the alternator as the revs drop and belt starts to slip.From various forums I have read of others who have done this and thought that you couldn't "overload" the alternator as it can only ever output it's maximum. Do I need to upgrade the alternator or just tighten the belt!
I've still not got a solution, I've charged both batteries up separately with a mains charger and tightened the belt but no joy yet. I bought two new belts this week and will fit tomorrow, fingers crossed!
