dumb move of the day....(car related anyway). troubleshooting a "tapping" noise issue. so, bought a compression tester gauge. The fancy one with braided hose. cylinders 1,2,3 went fine. on IV.....the hose was flapping around as I was threading it into the head and....BAM. opposite end tapped the battery + terminal and a had a spark at the head tin cover.
Then...it started to rain. so I covered the car and will go look tomorrow. so....did I smoke a relay? quick check, I pulled the coil wire off- pulled the boot back...long pliers and held it near the distributor cap center terminal, and have spark. (the coil was disconnected during the compression testing. ). When I turn ignition on, I can hear the fuel pump. (2nd dumb move of the day, don't pull the car out of the garage to work on it when thunderhead is rolling in....might not get it back in the garage). Thanks, best forum on the www. QM |

I’ll wager you’re fine.
Electricity follows path of least resistance. Engine is grounded. As long as it hit battery positive only all current flow was in the braid of the hose flowing between battery pos and the tin and/or cylinder head. Be glad it didn’t glow and burn your hand. Lesson learned. Next time disconnect battery negative terminal when threading that thing in. Better yet rubber hose. Nothing about 120 psi requires fancy braided hose. But of course I understand fully - braided hose sure looks cool. (IMG:style_emoticons/default/biggrin.gif) |
