I remember seeing a thread about various issues with this problem- bad relay, soft start module or bad battery. I have the original battery and understand that you have to change the tray to accommodate the smaller battery. I would like to troubleshoot my issue before I go that route. I do remember someone identifying an alternative battery that will fit. (Has anyone used an aftermarket battery successfully/) I have searched but just can't locate that thread. If I had a bad battery (charger shows fully charged) wouldn't I at least get a few clicks or something? I tried jumping but got same result- I get one humming noise on first try, then nothing-the humming is not like a starter spinning with low power but another sound between a hum and a buzz. Previously, I have had 2 bad relays, one for AC and the other for fuel pump. Which relay would I change to eliminate that being the culprit? I will try and bypass the soft start module if someone can confirm that it will not be detrimental if I just do so in order to isolate that as the problem. Any advice or help finding useful threads appreciated!
