How is everybody? I want to build an engine test rig & would like a simple wiring diagram including a tach & listing the different gauges of wire I will need. Can anyone post one or tell me where I can find one? Thanks for any help.

One of the easiest ways is to go with an MSD unit--you can run Mopar electronic, points, or any other distributor that comes along--As time goes by this works out well--your pals and other folks will bring lots of different stuff over to run and the MSD will do them all with a couple of easy hook ups--First time stand builders get a GREAT looking sturdy unit done the find out the headers won't clear etc--I will send some pix tomorrow of a decent design and include all the little things I have learned the hard way--My stand has been changed , cut, etc over the years--I can take a Mopar on and off in a few minutes be it Big, small or Hemi Start looking for a big and small block bell ( damaged, broken at the flea will mend up and do good CHEAP ) an old 10 1/2 neutral flywheel will run most but keep an eye out for external ones as they may pop up cheap--look for damaged clutch surfaces etc so you can get a deal--I had dented flea market headers but finally got some Motor home units that give lots of room with most any head and plug arrangement---a NEW good radiator is important! I found a Ford Pick up unit NEW for about $100 at local warehouse and the inlet / outlet works out well--I have the radiator on a frame and can put it on and off with one nut! Will PM pix tomorrow--call me I can tell you lots of little tips to make it smooth--and remember.... make a notch on it after every engine so you can keep count--It makes for good conversation later.

Awesome. I've always wanted to know this since electrical is not my thing. You don't happen to have this in a wiring diagram do you?

If I didi you probably wouldn't want to copy it anyhow. Easyest way is to use a starter relay and wire everthing from there. Diagrams are in tech archives. Good luck, and enjoy..You'll have a ton of fun with it...And probably scare your neighbors too

Forgot the voltage reg. Connect from the upstream side of the ballast resistor to the blue pigtail on the voltage reg connector & tee from this to either alt field terminal then connect the other alt field terminal to the green wire on the VR pigtail

U ise factory points distributors on mine. Never any isssues with no spark and they were free. It alaso means a simple on/off togggle can kill the ignition. I used a aftermarket horn button to activate the ford type starter solenoid and bough extra long cables. Gages are cheapo mechanicals. I have the tach in my timing light anyway, so it's just temp and oil pressure.

That's the diagram ya want to follow. I just use a $7.00 swap meetsnap on tach/dwell meter, the dual range function is nice.just needs power,ground and neg. side coil. Almost forgot, the toggle-kill is a great idea, I used a push pull type switch so when thins go bad you can "Push Off"...Less to remember when your imported silk tie gets caught in the fan..

Nah...That's my brother giving me some more of his "Advise"...If I don't do it myself it don't get done. That was Feb. 7th this year. Perfect weather for breaking in a new motor.

Mighty good stuff!! Thanks, all!
