In praise of the coil relay mod

[JEEPRUSTY]

I am going to do this I swear.
In testament to the parasitic loss of voltage in the long and much segmented ignition circuit I can state that I recently washes my switches in contact cleaner and the darned bike ran and started better.

I thought I cleaned em recently but the crap accumulates quickly in rain.
So a nice relay mod is in order,

I wonder what fallback you can have if the relays fail though.

Oh well!

jumper the relay plug to get home or carry a spare relay

you could also parallel a regular relay and a simple Solid State relay made of 2 mosfets (1 N-channel and 1 P channel)
like the attached.

the SSR is immune to vibration, but can be taken out by voltage spikes
a regular relay is immune to voltage spikes but can be taken out by vibration ... hopefully one of the two will survive any particular bad event ...

I did this redundant relay mod on my GPz and it works. Do yourself a favor and use a fuse block (I used a Blue Sea model 5028) and you will have a place to connect accessory horns, GPS adapters, iPod adapters, R/R sense wires, battery health wires and such.
