Dim instrument lights on my 5411B

[Larry LewisParticipant]

there is almost no light shed on the speedometer on my 54. I’ve long ago bypassed the dimmer switch, the bulbs are almost new and the speedo casing is earthed, yet the lights are barely on. The lights on my 49 BL are perfectly fine. Any ideas out there?

Hi Larry,

Unless your speedo glass is dirty, it has to be either a bad connection on the live or earth or a dodgy or 12V bulb.

Check the bulb directly on the battery.  If it is OK, take wires, +ve and -ve, directly from the battery to the light socket and see what happens. If it’s OK, remove one at a time and see which is the bad connection/broken or damaged wire.

If the bulb is OK but connecting wires directly from the battery does not give you a bright light, it could also be a poor connection between bulb and bulb holder or bulb holder and instrument case.

Hope this helps.

Roger
