I am having an issue with no spark on my 2wd YB, I am only getting 3v at the ignition coil when cranking, if I measure accross the + terminal and the chassis earth I get 12v. I don't know if the ignition module is to blame, the "book" says I should get 800 ohm if I measure the pins on the module but I get around 35k ohm when I measure. The module is brand new (from ebay that is) can anyone help? TIA
