Hi guys, hope eveyrone is having a good Sunday.
I picked up an Innova multimeter to measure dwell on the cars. Not sure what is normal behavior but it has a reading BEFORE I connected it to anything, meaning when I turned it on it was reading around 90 despite NOT being connected to anything. When I connected it to the car (red to - coil terminal and black to ground) I got a steady 69.5 reading. The 69.5 reading is a bit high but in the right range, but not sure how much I trust it given that I would have thought the meter would read zero when it was powered on but not connected to a signal. Anyone have a digital meter they use that could confirm normal/expected behavior of these things? Thanks! |

You should have spent the money on a set of Petronix and never again need to set dwell or replace the points. (IMG:style_emoticons/default/shades.gif)

(IMG:style_emoticons/default/shades.gif) Ha, and not a bad consideration but then I wouldn’t have been forced to learn anything new. Mark - Thanks for the article but I didn’t see if it covered the behavior of the meter itself, sorry if I missed that. I’m basically asking if I can trust the meter. |
