I smoked a timing light today


Recommended Posts

I borrowed a friends timing light today since mine is old and doesn't advance.  He has a one year old Bosch/Actron 7529 that he has used maybe a dozen times, I have used it twice before. So today I needed to use it again and had it on for about 10 - 15 minutes and got my timing set, then the strobe failed and soon after it started smoking through the cracks of the cheap housing.  I had it hooked up correctly. On-line reviews do indicate that the QC is spotty and many do fail.  Has anybody out there had bad luck with this unit? I gave him $80 for his tool, I don't think he will repeat his purchase though. I'm going to buy my own and not borrow his again.


Since I paid for it I'm going to take it apart and see what fried. At the very least I can salvage the leads, they are actually pretty good. But all in all this thing feels really cheap and the leads are actually too long for my taste. I'm looking into the style that has a hinge and the head is flatter and more rectangular. I think that will work better for the 02 since it can be fixed over the edge of the compartment with a wire harness for hands free use.

I had an OTC 3367 fail on me shortly after buying it.  Returned it through Amazon, went into Napa and picked up an INNOVA (bendy model as you mentioned you are thinking of) and it's still working a couple years later.  Not a lot of use, but neither did the OTC when it failed either...


must be the silver-esk coating

Mine is an Actron CP7529, but isn't marked Bosch, like the example pictured above. I've had it several years, using it dozens of times on lot of vehicles.  Works fine, every time.  Perhaps the newer units are suspect?  ...sux, because I've recommended this one to several people.



'69 Granada... long, long ago  

'71 Manila..such a great car

I had 2 Actron dwell tachs fail last year. First one dead out of the box, 2nd worked briefly.


Timing light still ok, tho with pretty minimal use.




Stop reading this! Don't you have anything better to do?? :P

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
