DSM 4g63 board confusion

Post by polarexpress17 »

i am having some trouble with a board i built for a 4g63. no RPM (pretty common)

i sat it up according to DIY's site and nothing. using an MSQ i downloaded from symtech, all settings match dieselgeek's settings, nothing works

Do i need a jumper in D1 or the diode? cause there is a jumper in there now.

Basically what would solve all my issues is if i had a board pic of someone with a working 4g63 installation.

Thanks

Yes, D1 should be replaced with a jumper.

ok so that was good, i couldn't find any definitive info but i had a jumper in to start with so thats not an issue. the underside of the board is identical to the picture on your site (with the exception of added output circuits)

Can you post your MSQ?

Does it get RPM if the Stim for Wheel mode is turned on?

FWIW, i have the CKP ran to the left (banded) leg of D1, because the jumper installed makes it the same as the right leg

A JimStim can supply the second trigger; the regular (4 or 5 LED) Stim will not. Let me know what Stim variant you are using to test this.
