My /6 conversion is going on 3 years as it seems as many do. I had a local old school reputable shop build the stock 2.7, case was done at Ollies, .... should be a great engine. Finally trying to get her barking, but just won't take hold. While cranking she wants to start, but when I release the starter, she conks out. We have a spark (not real significant), timing is close, carbs appear ok.
Is it possible the valves or maybe rings are not sealing because the engine sat for about 2 years? |

Checking ohms across the + battery cable (when disconnected) and the negative cable should be 0 ohms. Correct or incorrect?
This is confirmed with my well running 2056, 0 ohms Moving to my /6 conversion, not so. Checking across the + battery cable (when disconnected) and the negative battery I am getting 170 ohms Checking across one pair of red cables ( normally connected to the + battery cable) and the negative cable I am getting a reading of approx 400 ohms, but quickly goes to much higher reading. Checking across the MSD heavy red cable and the battery negative cable I am reading 12K ohms Currently putting a full charge in the battery, will try for actual voltage when cranking. I suspect there is a short or more somewhere. |

Short answer; with ignition off and both the battery + and battery negative (-) disconnected from the battery, you should see an open circuit (infinite) ohms assuming you have no parasitic loads like radio memory, the 914 center console clock, etc. Not sure how you could possibly be measuring zero ohms on the /4. Zero ohms would represent a short circuit and then when you connect the battery, the cables would get hot, melt insulation, and glow red hot. So you are not using the meter properly, or I’m not understanding what you’re doing. |
