"How to test coil??"
Remove battery lead from coil terminal and pull the high tension lead from the coil. With ohmmeter set to low scale measure resistance of the primary winding between terminals. Expect 0ne to five ohms but could be higer if coil contains a current limiting resistor. It should not read a dead short or extremly high. With the ohmmeter set to a higher scale measure the secondary winding by measuring between the minus terminal and the high tension contact. Expect 10-15 thousand(k) ohms. If these tests pass you probably have a functioning transformer. Large discrepancies should be suspect.
