Default Sun Tach Transmitter (Batteries?)

Hello guys,

My car has a Sun Tack from 1958. I was told there may be some kind of battery inside. Does this sound right?

Is there anything inside this box that needs service after sitting a long time?

Also, does the tach need any lubrication?

Thanks for the help!

There is two batteries innside, but the problem is that they are discontinued. If i remember right, they are connected in serial.
Each battery is rated 1.35Volts. Combined it's 2,7volts.
I made a external powersupply to give exact that power.

When opened up, you should also messure the capasitors.

There are two 1.3 volt mercury cells inside. If they are still there and have been leaking you have a problem. If not then you can use 1.5 V AA alkaline batteries. It will make the tach read about 10% high. There is a company that puts new guts in the old senders that makes the tach read right and its all solid state and runs off of 12V so no batteries. THey also can put new guts in the meter head itself so the sender isn't needed. Both are $200 or so. You can check the meter with a 1.5V battery to see if its good. Just connect a 1.5v battery to the + and - terminals on the back of the meter. No lube required on the meter.

Yes,there is batteries inside..called a "Mercury Battery"..no longer available..
The transmitter box you have shown needs to be matching to your number of cyl and voltage.. Williamsons in Chester Ark.does a fantistic job on bringing these back to working order
