I have only ever used an old school sun timing light that is not digital...Is the actron light that you use this one here? They make a digital one as well, not sure what the benefits of a digital light are though
I have the digital Actron. It will show rpm, is switchable for 2 or 4 cycle, has a flashlight mode and can be used as a dial-back. I just leave it on zero.
MSD says no dial lights to be used and if you use a traditional 12v light, to use a seperate 12v battery to power it. I bought a MSD self powerd light, later found out it is a Ferret #81 light, works great and no power pigtail wires to hook up to 12V! That is a bounus on some cars..
Works great! And I like the quick disconnect spark plug induction, ask me why?!? I did the dumb thing and burned it, but a new one was like $15.00 or so, I ordered 2! And I liked it so much I bought a Ferret digital dial with tach and dwell, also does 2 stroke among other things. Great for my antique cars to tune.
That's a good tip, I always use a small 12v lawnmower, motorcycle battery instead of the 16v car power.
Which as mentioned, some of us have no choice, there is no open power anyway on my T/S car unlike my other cars.
