Electrical stuff is kinda my background so yeah, plenty of spots to check. From memory the starter on this is fairly easy to get to. The body to battery ground really doesn't look the beefiest either, so that will definitely be getting checked. The battery terminals have been changed - though there's no guarantee they've been fitted well...MattBLancs wrote: 11 Dec 2022, 23:22 Probably stating the obvious, but check the earths as well as the starter's 12 volt feed - both could be showing the strain when starter engaged.
I'd try multimeter tests as follows:
- Battery voltage, after sitting over night,
- During cranking,
- Measure volt drop battery terminal to engine block during cranking,
The above should tell you where the power is going (or if all seem good, that the starter is just not very efficient)
- Measure positive connection to starter to battery positive during cranking if it's accessible enough to do so.
Wow loads of room, those cable drums are pretty bulky surprised it slips in with ease!
Looking at the pattern in the adhesive mark, it looks like duck tape to my eyes. Think it does eventually give in to WD40 but also goes funny when exposed to UV - which of course it would do sat on the dash top. Any clues what it might have been for? Seems odd position.
I may well be chasing nothing, I seem to remember these starters always sounding kinda like they're on their last legs on my 11, a friend's 5 and another 21 but don't recall any of the above actually having any issues, they just always sound like they're labouring.
For the tape on the dash my guess is holding the glove compartment closed.
It's worth keeping in mind that this car was off the road for 11 years prior to being resurrected in 2017, so who knows what happened to it during that time.
I'll spend a bit more time trying to clean it when I'm not trying not to freeze to death!
