28 Dash light intermittent operation
Hi all,
Picked up a really nice plated dash for my car. Has the original oval speedometer and dash lamp. My problem is the lamp won’t stay on. It will come on when I turn it some but it’s off when either in or out. What’s the best way to take the lamp apart to clean and service it since I’m sure after 90 plus years it could use some service. Hook me up guys. Thanks, Cliff Ramsdell |

Re: 28 Dash light intermittent operation
I guess my reference was to the lamp socket. It appears that the socket, when twisted, moves in and out making contact.
Has anyone taken one of these lamp switches apart? Cliff Ramsdell |

Re: 28 Dash light intermittent operation
If the springs are rusty it will be difficult to operate.
I soak them in evaporust for several days to remove the rust, I then put some light oil in them to make them turn smooth. There is a small spring under the contact that hold the contact against the bulb, if this spring is broken you will need to replace it. The contact must move in and out freely with spring tension. I then replace the wire if necessary. |

Re: 28 Dash light intermittent operation
The outer housing should be pressed in slightly and turned to the right and have a noticeable stopping point where it sort of clicks into an open position and the bulb will stay lighted. The bulb does create a lot of heat and the outer case becomes quite hot, making it difficult to turn off.... perhaps why it is not meant to be on all the time, just intermittent. press it in somewhat and look at the speed and/or gas gauge and let it return to the off position.

Re: 28 Dash light intermittent operation
Thanks for all the tips. I cleaned the lamp assembly in the parts washer and then some carb cleaner. Some spray white grease and she works great.
Thanks, Cliff Ramsdell |
