Tach. Input Circuit.

Post by Wally18 »

Good Day Matt,
Would you kindly advise me on this wiring issue, please for my MS 11 V3 board
Reference item No-52 in the construction sheets---- "Selecting the Tach Input circuit jumpers".
I am using a EDIS4 Ford timing system, so I use the Hall Optical Circuit
With regard to the 3rd., paragraph and the note to jumper " TSEL OPTOOUT". There are 2 solder wire locations near the "TSEL" printing on the board---and then a further 3 solder locations at right angles, which are marked "OPTOOUT.
Between where should I solder the jumper lead?"
My thanks for your help on a minor matter.
Regards Ian Cowen.

If you have fitted the surrounding components, there should only be three remaining choices in that area. The two nearest the power transistors are Tsel and OPTOout. The one beneath them is VR out. This might help:-
