story:
at the last minute I swapped from my bat-a-cap battery with bolt down terminals, to a stock sized battery due to my cold start settings not being good enough in the 50 degress weather (i live in FL sue me, its ****ing cold) to start before the little battery died.
i cheaped out and used my old marine style battery terminals so I did not have to build new leads ect.
well everything seemed fine and the terminals seemed snug. that was until my first pass at this weekends NSCRA event, where after my burnout I staged and launched only to have the car die instantly.
after getting off the track it turns out my negative terminal jumped right off, easy fix right? nope... put it back on and get nothing but the sound of the starter turning in vain.
alittle troubleshooting turns up my megasquirt was not booting up. there was power to the 12v lead, so I pulled apart the MS to find this:
look between the IAC1A and IAC1B markings and you will see that the +12v lead burned right the **** off due to the voltage spike my cheap plan caused.
in the end as you can see i made a jumper trackside and continued my day, but it very well could have been the end of the race weekend and a huge waste of money if i wasnt able to solder it back together.
