Hi

I'm looking to replace my dual battery solenoid which is simply connected when the ignition is on with one of the voltage sensing types.

I'm still trying to figure out if my alternator is 100amp or higher. If higher I won't be able to use the common Redarc SBI12.

I noticed supercheap sell a Ridge Ryder VSR at 140a quite cheap.

Are these things any good? Once you get over 100a rating prices get really silly.
