Help with Temp, Gas, Oil Alt gauges FREE VIDEO INCLUDED!

Clip leads to extend the leads work too, and you can use them for other work too. I would not do that for high voltages, but for12V and voltmeter they work fine.
OK, ill look for some. now just to be clear, Im hooking the ground to the bat neg- terminal and then getting underneath my dash while everything is still and touching the red lead to the IVR to see if its close to battery level around 12.65 off and 14.50 running? That seems doable, but stupid question how are you able to touch all the other points? I cant take my dash out and still have it con?nected...
