I'm pretty confused about something when it comes to wiring up the probes for Fuel and Oil Pressure. The manual states that any Type A GP input can be used. Ok, no problem but also, there is mention of connecting each probe case to a common ground to the EMS.
Ok, no problem but what has me wondering about the wiring is the fact that there is no resistance between the probe's terminal and the probe's case.
In other words, taking my digital meter and checking for ohms, it's pure zero. I put the meter on the most sensitive setting too, zero ohms.
So, What gives? Do I ground to the case by some method or do I just connect the ground to the terminal along with the GP input wire since it would be the same electrical result either way?
I actually spoke to somone at tech support on this topic already and they did mention that there is "some" resistance between the terminal and the case. If it's there, my meter can't see it.
Thanks for the help...
