    750sx help!!

    Hi All, looking for a bit of assistance. Had my 750SX for a few years now. Year 1 running great, however towards end of season wouldn't start. Started the diagnostic process and decided the stator was at fault. Replaced the stator, however noticed the bendix was faulty, whilst I had the cover off, so changed the bendix too. Connected it all back up, still nothing. Did more diagnostics and figured it must be the coil pack. Bought and replaced this, built it all back up and started right away. Got about half a season out of it and it would start first time, go for a splash, came in and beached, then went to go back out and wouldn't start. This happened a couple of weekends in a row, however then wouldn't start at all. Checked and random sparks, not consistent and eventually weak. I ordered another coil pack, replaced this and still nothing. Before I open up the stator cover again, anyone any thoughts on what could be the problem?

    Have you checked the compression?

    If that was an aftermarket stator I would go through the testing procedure again. Aftermarket electrics are sketchy at best.

    Sometimes this can be caused by the starting circuit taking too much power. In this instance the starter is usually the culprit when it takes too much energy to crank. But it can also be bad connections, bad cables, a bad battery, etc. If you measure the voltage while cranking what does it get down to? Anything lower than 10 volts could cause a failure to spark.

    Thanks for the advice everyone, will try a few things. The cranking feels fine and will crank over several times, although my battery terminal connection is not the best, might investigate that first!
