This is one of the early timing lights I've had .. There is a spring that goes between the #1 spark plug and spark plug wire .. the red lead clamps onto the spring ..
Spring?? If I don't have the spring...?

Man I miss timing lights ... it would always amaze me how the line on the harmonic balancer would stay still even though I knew the balancer was turning.![]()
Wow -- it's getting pretty interesting when only a few guys remember how to hook up a standard timing light. Those Penske lights were a Sears staple. They must have sold hundreds of thousands in the 1970's. It was one of the most afordable "professional quality" timing lights at the time. I'm not sure if the Pensle lights ever came with an advance.

I still have one or two in the bottom of the tool box junk drawer. Got many a fumblucution over the years hooking and unhooking while the motor was running. Still use timing lights but have moved on to a digital inductive with advance and RPM.Wow -- it's getting pretty interesting when only a few guys remember how to hook up a standard timing light.

It had a bright white xenon bulb which was a huge improvement over the older yellow/orange neon bulbs in the older tube lights; which were hardly noticeable in broad daylight. That's a nice piece of automotive history.
BTW --- BMW -- you can take any small stiff spring that will fit on the end of the #1 spark plug, and that will also allow the plug wire to attach securely to the other end. Then just clip the red lead to the middle of the spring.
Next thing that will happen is threads asking what a dwell meter is.
I'm suprised that nobody said they kept an ice pick in their toolbox as standard equiptment as a mate to the timing light and you just jobe into edge of the #1 plug boot or into the distributor cap position #1. I have an old neon, Sun, and SO and never had an induction model. I quit wrenching in 1978 to start a carreer as a phoneman with Bell.
That and the 20ml syringe with a 16 gauge needle on it confuse most of our younger employees.
distributor cam?Great thread!! Really shows the difference between us older guys (Yes, if you're over 40 your "older"!!) and the young bucks!!!
I too have an old timing light. I read about newer inductive models in the mags, but haven't tried one, since the only vehicles I work on are older thatn 74! Our new cars are dealer-service only...
Tell me about these inductive ones with mag pickup!!![]()



Wow, some of you guys are really old!![]()

I that same light and still use it, not on my DD of course.
You keep talking like that and we're liable to throw some round fuses at you.
Now, off to my garage to look at my timing light and my dwell meter.

On the matchbooks, when we ran JD 105's and 95's they were hard on points so occasionally they would just die when running at full power the points spring was always broken. So we set the points at least a couple times a season with matchbooks.
My ford has the #1 cyl on the drivers side with the timing pointer on the drivers side. Extra length comes in handyI have a very similar light and do not have the spring. I just remove the spark plug wire, take a smaller gauge wire with the end stripped and wrap it around the spark plug tip, then put the plug wire back on over the plug and wire, then use the alligator clip on the light to connect to the wire. This prevents the spring from arcing against the block, and you can make the wire as long as you wantMy ford has the #1 cyl on the drivers side with the timing pointer on the drivers side.
