Voltage across IC1
My kit arrived the other day & I've started to put it together, never done any electronics at all before. Soldered the first few items as per the HowTo & then have checked the voltages. I am using an AT PC power supply which is putting out 11.69 volts, all the 5.0V are correct but across IC1 it says you should have either 12V or the input voltage (assumes means 9V if using a battery) I am only getting 11.13V which is over 0.5V down is something wrong? Do I need to recheck all joints or can I proceed.

Using a 30W iron is that suitable sorry if it's a dumb question but as I say this is all new & quite exciting to me, especailly if it all works. Done the next section & tested voltages, all the same so tomorrow I will install the active components (MAP).
Just got to sort out a pully, it's going on an A-series engine in UK, quite an expense item over here.

30W is fine. Here's one of many soldering tutorials out on the interweb:

That should be ok. The important bits are the 5V across all of the active components. I think you're doing well so far.
So you're installing a new ignition system *and* stepping into the world of electronics. cool!

--I had to put a 6 foot piece of pipe on breaker bar for the axle nut! One axle came out, and the other is still frozen in the hub. Hopefully the penetrating oil I soaked it in last night will unstick it.

Sorry to resurrect this, but I have finally started assembly of my Megajolt Lite Jr (I use it's full name out of respect ) and was trawling for the answer as to why I had the 0.5v drop mentioned here (12.3 to 11.8 on a motorcycle battery in my case) and I just thought I'd point out that the instructions still say "Verify +12v (or whatever your supply voltage is)." - did you amend them somewhere else? (Higher up this topic you said "Good! I updated the instructions to say "Close to supply voltage"")
I am also stepping into the brave new world of electronics for the first time, and am enjoying it immensely - but I think that this is mainly due to the clear instructions, the clearly labeled packaging and the quality if the PCB. (see I'm getting into the jargon already)
Thanks Brent! Great piece of kit

Thanks! I glad for many the benefits for the MJLJ are multi-faceted. As I've said before, I've learned a lot in the process as well. I trust it will show in our upcoming projects!
At the time I was really regretting digging so deep into the M3's suspension, just to replace some sub frame bushings. Now that it's done and time has passed, I'm just blown away at how GOOD it handles. It's truly an amazing machine.
However I think I forgot to stake the rear axle nuts... I should fix that soon.
