Re: Pulse Pack
Jonesy.... I received your e-mail and have answered it a short time ago. I'd suggest that you check the compression, should be 100+ psi and even on all cylinders. Also, with the s/plugs removed, check the spark... should jump a 1/4" gap on all cylinders.<br /><br />Your problem does sound like an ignition problem rather than a fuel problem as a fuel problem would have the engine spitting and sputtering, then gradually run out of fuel and stop. However, a ignition problem (suddenly losing spark) would, as you have stated, stop the engine suddenly.<br /><br />Should you reach a point whereas you know for a fact that you've lost ignition (spark), your powerpack on that model can be tested as follows:<br /><br />(Battery Capacitance Dischage Powerpack Test)<br /><br />Purchase a small 12v bulb at your local automotive parts store (the 12v bulb is to look like a flashlight bulb, not a headlight bulb). Solder two wires to that bulb, one to the side of the bulb (ground), and the other to the positive point. <br /><br />Remove the spark plugs. With the key in the on position, make sure that you have 12v going to the pack at the terminal block (purple wire). Now, connect the ground wire from the bulb to any powerhead ground. Connect the wire from the positive point of that bulb to the powerpack wire that is connected to the coil wire on the terminal board (blue wire). <br /><br />Crank the engine and observe that bulb closely (CLOSELY!). If that bulb glows even the slightest bit, the powerpack is okay. It may be a very dim glow... just so it glows! If it doesn't glow, the pack has failed. <br /><br />Keep in mind, that type powerpack (Battery Capacitance Discharge) demands a top notch battery of at least 70 amp hours. Any less will, in time, cause powerpack failure.
