Fair warning, be certian to check a new Smiths volt gauge b-4 you put it on.
I installed it today only to find out the pos didn't even budge. Foiled by Murphy again!
Yes I double checked it by hooking it up direct to the battery with #1 post going to ground and #2 to the + of battery.
I called Nisonger this morning and they will repair or replace the gauge but they won't spring for the return shipping.
Pi$$ poor customer service I think!
