The Sun tachs that were used on our old trucks had transmitters; the
transmitter for the V8's was an EB-9A. I'm starting to collect some parts for
these and need info from someone who already has one.
These transmitters have a mercury battery in them.
1--Since 12VDC is supplied to the transmitter anyway, what is the mercury
battery for? DC offset for the trigger?
2--What is the voltage/current rating on the battery and is there an equivalent
part number/product for any modern part?
3--I'm assuming that any 40 something year old battery will be bad. . .correct?
I feel pretty comfortable finding replacement parts and replacing any
capacitors, etc in the unit but the battery makes things interesting.
Thanks for any assistance,
