If You don't have a Multimeter...
or anything else....
Take the bulb out of the speedo or else use a small bulb -
and take a battery lead off the battery....
Now place the bulb up against the battery lead clamp and touch the bottom of the bulb on the battery terminal...
This means if any power is being used, it has to go thru the bulb and the bulb will light up if any power is going thru it....
Just make sure the bottom of the bulb is touching the top of the battery terminal and NOT the cable itself...
Best bulb to use would be 12v 2.2w or 12v 4w or 5w....
this will show any small leakage of power....
If the bulb doesn't light up - get someone to turn the parking lamps on while You hold the bulb on the battery terminal...
the Light BULB Should LIGHT when the parking lamps or anything else is turned on....
Before doing this... Turn OFF the interior Lamp.....
cheers
