Content-Type: text/plain; charset=us-ascii

Hi Ron & all,
 I am wondering if anyone other that Sean B & myself
have tried the Hella battery relay from Bus Depot &
found it to be worthless?

I installed exactly like the instructions & when you
turn on the ignition, the fuse pops immediately. Sean
had the exact same problem & he feels it's the tiny
little wires can't handle the load. I feel the same. I
went with Sean's solution of using a large relay from
Newark Electronics, (idea originating from Mark
Drillock) & have had no problems.

I was wondering if anyone had the Hella actually work
& if they can explain their installation? Ron, any
comments or complaint stories?

I am afraid of the starting battery being effected by
a low aux. But am considering adding a toggle to
disconnect the aux for starting after heavy usage.

Any insight appreciated.
Thanks,

David K.
