old msd total loss wiring diagram?

I have one of the older msd total loss systems that have the plug in chips for timing and rev.does anyone have the wiring diagram for it,its no longer on the msd site.

I'm sure I have them in my bottom drawer in my toolbox, if you can't find them... Call the shop/email and have Radney copy them on the scanner and email them to you.

pg 54, for wiring diagram

I couldn't get it right yet. Timing would be good not running or running out of water (tried25 to 36 deg.) but would not start and run consistantly. Backfiring ..etc.. I found my timing retard start chip was nfg. Checked with ohm meter and it had nothing. took apart resistor was all corroded and broken from pin, cleaned resoldered and was ok. Put in water and still backfire barely run. If you have a rev limiter chip can you test out the resistance and let me know what it is? and I'll make one because no one seems to have one. Mine had the wires cut but when I got the wiring diagram I could see the 2 grey wires should run to a rev limit chip. I don't know if they are needed to go to a chip or if the unit will just have no rev limit. I think this weekend I will install a stock ign setup I must have some more bad connections somewhere and summer is almost over.
 
coldblaster,click your link,its niot working for me. I do have 2 chips on the ign not sure what 2.My meter has been not working right,ill try and borrow one and get a limiter resistance for you

Also check and see if you have one of the older analog systems that require you to set your static timing 5 degree's more then you want.... so if you wanted it as 22 deg you'd set it up at 27 deg... ect. Call up MSD, they'll then which ones require that.
 
thanks Chuck and Radney for the msd pics and the wealth of knowledge on setting up the head mill and the msd inj. Chuck is unreal at what he knows on the setup of these yami motors

coldblaster..thanks also that link does work,dont know where you found that on their siteI had no luck finding it
