I have recently rebuilt a Tohatsu 15 hp that I bought second hand. After reassembly and reconnecting the wiring I found that I have no spark. I have checked and rechecked my wires and all are correctly grounded and connected. I spoke with a mechanic at a local shop and was given the omz values on the electrical components. After checking all of them, I did not get a reading on the exciter. I was told to set the meter to "200", and the reading should be 163 omz +/- 20%. Although the meter I have reads that low, it is not much of a jump from 0 to 200, and it is generic one size fits all meter. Should I go ahead and replace the exciter or should I get a meter that I can dial to "200" and recheck. Im working on a limited budget and cannot afford to waste money on parts that I dont need. Any thoughts are appreciated.
