I went with the Hot Spark that replaces the condenser and the points in the disty. After 38000 miles.... maybe 10000 with a new voltage regulator I determined that my module was seriously acting up. That's all in another thread.
This thread is for helping me make sure I don't have problems down the road, so chime in if you can help. The manufacturer recommends, actually requires that you only put 13.7 volts at any RPM into their module. So I tested it after I put my spare module on the car. My 75 L-Jet 1911 cc engine idles perfectly at 950. 1 VOM lead on the coil + the other on ground. Results of the test are as follows: voltage at Idle.... 13.9 -14.2 fail (IMG:style_emoticons/default/barf.gif) voltage at 4000 rpm... 13.6 - 13.9 fail (IMG:style_emoticons/default/barf.gif) Hot Spark says to put a 1.4 ohm Ballast Resistor between the module and coil +... Moved the VOM lead to the exit end of the resistor. Idle....13.9 - 14.2 fail (IMG:style_emoticons/default/barf.gif) 4000...13.5 - 13.68 pass (IMG:style_emoticons/default/KMA.gif) Tried a 5 ohm Ballast Resistor Idle...13.95 - 14.02 fail 4000...13.57 - 13.61 pass 5 ohm BR and the headlights are ON Idle...12.28 - 12.32 pass (IMG:style_emoticons/default/cheer.gif) 4000... 13.29 - 13.31 pass (IMG:style_emoticons/default/cheer.gif) Now I can't drive around with my headlights on all the time. 2ndly I would say that the % of idle time is way less than the 3000 to 4000 rpm driving time. What are your thoughts? Why do I see no change at idle? What else is out there to use instead. This module is only $35 so I figured it was cheap technology. It was simple and maintenance free. Bolt it on and plug it in. |

In helping others with their Ljet issues, I have found a few hot spark modules acting goofy. Currently, the hotspark module in my 914 is acting very goofy and is misfiring at idle (had it for over 5 years). I was a huge proponent for this 30 dollar module, but now I'm steering folks away and advising the 123 dizzy instead.

When it gets to the top of the list, I will get the 123 dizzy, it looks and sounds like a real nice upgrade, but 5 years out of a $30 to $50 part is a bargain. I haven't even had the cap off the distributor or adjusted the timing after all the miles and time! |
