Normal voltage using digital volmeter

[aioshin]

yung ginawa ko sa digital voltmeter ko e nakawire ito directly sa battery via a relay para hindi na kasali sa reading yung voltage drop sa wiring within the dash.

Relay control circuit: wired to IGN ON
Relay load circuit: wired to battery & voltmeter.

Ayos, thanks for sharing the idea, lagyan ko din digital volmeter yung sa kin para monitor palagi ilang voltage when using the car.. Salamat Miked
