if connect it to fuse....i wil try la....any fuse wil do rite?

if you have those 12v test pen then test which fuse that has the power during the the key is on ignition...if not the meter will be on 24-7 and might drained the battery...try the meter fuse or radio...these 2 fuse are on only during the key is on the ignition...good luck...

best if you conect the meter + wire to the + side battery with a relay. this way the meter will read the true alternator output, not sharing it with another electrical or electroic unit.

err ok i try but correct me if i'm wrong, its been while

- wire in the volt meter's ground and light wires first.
-get a BOSCH relay (better reliability). underneath there will be a set of numbered conections: 87, 87a, 86, 85, 30.
- ground the number 86 and conect the number 85 to your ignition.
- connect the number 87 to the + wire of the volt meter
- then connect the number 30 to the + battery terminal
