Caterham won't start (with video!)

[HustleRussell]

I started a thread in GG here but thought I'd better ask in technical.

Random starting issue. Once push started, the car will start pretty reliably for the rest of the day- but if left overnight, this random starting issue rears its ugly head. Battery is charged and fine according to a battery analyser. Starter motor has been refurbed. video here

The electrolyte bubbled when the starter motor guy connected one of these to it;



Never seen one of those used before so had no idea what to expect... all 6 cells were slowly bubbling after less than 10 seconds of the load tester being connected.

I have ordered a new battery this morning but as some people in the other thread were saying having watched the video it is unusual what the starter motor is doing and it does seem like a starter motor fault. I'm sure the battery is past it, I just hope I'm not in for a new starter motor too.

It's a conventional pre-engaged starter

Well you were correct, new battery fitted this morning and not a jot of difference, checked for wiring issues this morning and everything was perfect, starter motor back with the refurbishers now for warranty repair. Seems the ratchet / pawl mechanism in the pinion is not locking the nosegear to the shaft.
