i'm going to replace the gauge anyway but mainly i was trying to see if the sending unit resestor was reading like it should.
see i change the sending unit line from 5/16 to 3/8 for my hemi project. i couldn't see paying about 150.00 for a sending unit i can make. i'll post pictures later.
besides the new one i bought for the duster don't work right (but i never checked the ohms)
