This was a big problem with me lol. I ended up buying a set of high heat plug wire insulators like shown in the video at 8:33 .

You should get some spark plugs. It will run a lot better with them.

Get a peugeot 205 gti ignition

This box doesnot change the timing. And your timing is much to late. At leat 10 to 16 before tdc. Depending on your cam

Tach works off coil

Leave the HEI in there, no need in that car

check summit racing. it will tell you what fits

Yep, I just lowered the play-back speed.

Run the thick red wire to power side of starter solenoid and ground strap on engine to frame for negative

@@culbycars no, run it directly to the battery, just like the instructions say to do.

Run it to your main power distribution in the front of the car.

Old cars, fixing them up and changing the ignition system

@Cam montreuil engines I found that my 12 volt on battery supply was of not working

The box gives you strong multiple sparks which are greater than a stock ignition system. I have a 6AL model 6420 which is analog and not digital cause I didn’t want the known failures of the digital box since the new boxes are made in China. Pick up a used one that was made in USA.

@@johnmilner7603 Yep, I have the same U.S. box. Running for decades w/o a problem. It's also under my dash and away from heat.

I have had this same box on my 1965 Mustang 289 using a 1985 5.0 stock Ford distributor, stock cap and rotors and 1985 stock Standard Igniiton coil for 35 years. It still runs perfect. And in 35 years I have the same components: distributor cap & rotor , coil, plugs, plug wires. I have never touched it since I installed it. Now I can't comment on any made in china box. But my US made box is great. And now having the internet and videos, great. 35 years ago I had the manual. Engine: 289 bored 40 over, REED cam, dual plane manifold with a 650 Holley, roller rockers, 5spd TREMEC, aluminium drive shaft, 3:55 possy dif. And for anyone who had read this far, if you want to know my personal modification using all original parts to get the car to handle better than a Shelby Mustang, and no nose dive. The car sits level, with 1968 Mustang big block coils with 1/3rd coil cut off. The trick is a little mod on the upper contro arms. When installing new upper control arm bushings shift the shaft rearward giving you more caster. And I hardly have any shims, whcih almost hard mounts the upper arms to the frame. Finish it off with a half leaf on the rear leaf spring. One inch from and 11/16th rear sway bars using adjustabe heim joints. My small claims to fame as a custom car builder: I built a AC Cobra that holds the track record at Road Atlanta and I built the prototype AC Cobra for Exicalibur Motors. I miss those days.

Msd will say yes there wrong I had 2 new ones there cheap made in china older ones better how can a coil work without 12 v to + side of coil mad was trying to tell me it's normal..lol joke the wires inside box are cheap brittle try progressive ingnition new but cool you can also use just a ,4 pin GMC ingnition module msd even makes one ..msd ignition boxes are junk

@@michaelgilly2423 the coil gets a pulsed voltage only when it should spark. This voltage is higher then the normal voltage. And is not constant

2 boxes same 4 volts even wen cranking ...never gets close to 12 volts boxes do not work

So how does it start also wen running how would it ever show a dip at coil not to mention at rpm how would it have time to pause the 12 volt ? There's no time box has power shows pulse from distributor ..won't start because no 12 volts at coil..lol it's negative volts my brother reminded me tested with 2 new boxes 4 different new coils spark from coil solo weak...12 volt power from key to red wire 2 wires to ingnition 2 to coil plus there +- to battery simple seen read slot on thoes boxes not working rite or they work then not from plastic piece falls off breaks thin wire goes to coil how could it not have 12 volt at coil ??? To start plus it's fiering all the time so it's gonna be 12 volt all the time has no time to go to 0 volts then fire again every ingnition system has 12 volts or ran thru ballets but always shows power wen cranking there's nothing no volts at all

No they will say yes but it's BS ....there trying to say it only has 12 volts wen foreign..lol so that all the time I tried 2 boxes 4 coils same nothing I went back to my gm 4 pin on my Mopar ...boxes are junk...no 12 volt at coil.ok wat about wen cranking?? Still none

😂😂😂

That was kind of funny about not making sense especially if you have little knowledge of a basic distributor with a point system 🫤. I do believe if you're really into getting the most out of your vehicle you would put the effort into it it would be very well and a learning experience good luck.

Me neither. I have one on my satellite and no clue how it works.

Neither does joe biden.

CoViD is the new excuse for piss poor customer service by companies

Red to ignition on, make sure it's hot during cranking as well.

They stole my battery

@Cam montreuil engines why are these junk? I know nothing about them . Wanting to boost spark on my toyota 3k corolla engine

I blew the first one up on my boat and it was my fault because I had dead batteries and had a battery charger on battery on 12 v crank assist and it fryed the box. It was the 6btm. The second one just stopped working but I was careful and did nothing wrong this time. Lasted 5 years. But price went up 400 Canadian since 2019

Why is it bad

set it for 4 cylinder. yours had redundant plugs (two) per cylinder. It's still a four cylinder.
