This is a very timely discussion for me, as I'm putting in a hard
start relay right now. This is something I'm just wiring together
myself (wasn't aware of Jay's kit when I started this), but it's
following the WR-1 schematic, which is pretty straightforward.
However, right now the starter solenoid is not disengaging after the
engine starts. After the engine starts I am seeing around 8V on the
starter wire, which evidently wasn't enough to trigger the solenoid
but is sufficient to trigger the hard start relay.
The site below mentions that this can be a problem with GoWesty's aux
battery kit. I don't have that kit, but I do have a similar setup with
a relay, triggered with the wire that used to trigger the fridge fuse.
One difference is that apparently GoWesty's kit suggests cutting into
the wiring behind the fuse panel. I have kept all that stock, and am
using Mark Drillock's trick of pulling a wire from the aux battery and
plugging it into the #3 fuse instead.
BTW, my first suspicion was that it was related to the ignition switch
(current bleeding over from the #15 terminal on the switch to the #50
or the like), so I pulled the ignition switch altogether, but the
problem remained. Haven't had a chance to rip out the aux battery
relay yet to confirm that it is the source of the problem. I'm sure a
lot of people are going to jump in at this point and tell me to use an
isolator or ACR instead. I do like the simplicity of the relay, and
even if I wind up replacing it with another solution I'd still like to
understand how the aux relay would interact with the ignition circuit,
if nothing else for my own edification. Seems to me that they *should*
be completely separate.
Anyone else seen something similar to this or have any ideas?
