Hi all. Under these conditions: - grounds between engine and frame cleaned and ok, new braided strap between engine and frame - battery negative clamp dis-connected, ECU dis-connected - VOM probe to new braided engine ground strap or various points on engine metal. - big brown ground wire in ECU harness re-connected to bare frame metal near ECU. (this made no difference to engine performance) I should see continuity between pin 4 of AFM plug, ground wire of temp II sensor, ground of throttle valve (enrichment) switch, pin 6 of ECU, and engine metal or frame correct? I don't. Measuring between pin 6 of ECU harness and new ground point near ECU, I see a huge resistance or infinite Ohms. Re-connecting battery ground should make no difference correct? Engine runs "ok" so what am I misunderstanding or doing wrong? I have not inspected ground strap between transmission mount and body, but wouldn't a clean ground at ECU, and clean grounds in engine bay, suffice for the above tests? I have checked with 2 different VOM's. Neil. -- Neil n 65 kb image Myford Ready For Assembly http://tinyurl.com/64sx4rp '88 Slate Blue Westy to be named.
