Dual Batt System and now no Start

Ok guys
Now its my turn with some problems.

I installed a dual batt system, Redarc isolator and two 100amp circuit breakers close to each battery, All positive wiring was done.

I had not yet got around to connecting a negative/earth terminal to the aux batt.
I connected a jumper lead between both negative terminals just so i can test the system.
I started the vehicle and turned off and since then each time i tried starting it sounds like the main battery was dying (not enough power to crank).
The jumper lead was removed from neg terminal and still not enough cranking power.

Just managed to start this morning and get to work, that should have been enough time to charge the main batt, and now it wont start, i only get a click from the solenoid on the starter, I tried jump starting and still no go.

All i get is a one click from the starter and no cranking, Could i have done something to stuff the starter ???

Are the battery terminals on your cranking battery clean and tight?
Hey Jimako.

It's good news that you got it going, I just have a couple of questions.

When you "put it straight on the spare battery with jumper leads and got the click but no spin."

How did you connect this?

Neg to the body of the starter motor and the positive to the?, terminal where the smaller wire goes or where the battery cable connects or both?

What did you find when you pulled the starter motor apart?

Was the starter motor playing up before?

I cant see how you could of damaged the starter motor by installing the second battery.

I would have to agree that it was just a coincidence, I just cant see how anything that you could have done while installing the dual battery could have caused this.

What engine do you have? I seem to recall reading a few threads about starter motors s**ting them self without any warning especially the 4.8
