I have a msd model #4270 on my jetski and I am having problems with it blowing fuses. I have disconnected all wires but the power and ground and they are still blowing. I think it might be shorted out but it was working fine a few months ago and nothing has been done but taking out the battery and putting a new one in. Can anyone help me. thanks

Inspect the red wire coming from the 4270, make sure the red insulation covering the wire is not exposed or grounding out to anything on your jet ski, if the red wire checks out okay then itís possible that the 4270 is shorting out on the inside. The unit can be sent to us for testing.
