Hey fleetman !
(same fleetman from srv540 board?)
Anyway, it looks like the difference between the two switches is the ones for the other vmax's and the srvs, etc, have a plug with 2 terminals in it while the vmax4 plug has a plug with 4 terminals in it. I looked at the schematic however and I am sure I could retrofit the 2 wire plug. Looking at the schematic, it shows that in the off switch position the fuel meter is disconnected from power, when you turn it on it is connected. The other two wires simply ground out the ignition like we are all used to. I'm sure the reason they disconnect the fuel guage is to make it read correctly even after the engine is turned off. There is a condensor in the circuit (capacitor) that will hold a charge to the fuel guage as long as it can't find a path to ground, if the rectifier/regulator isn't disconnected from the circuit condensor, i'm sure it could find a path to ground and the fuel guage won't read correctly when the ignition is off. So, if I connect the fuel guage wire permanently to the power lead, and connect the 2 wire switch for the ignition, the worse thing that happens is that my fuel guage is wrong when the sled isn't running, i could probalby live with that.
--unless of course somebody has the right switch ? I hate to spend $40 just for having the fuel guage read correct when the sled is off, and i have an srv switch.
