99 sub-genres, but Screamo ain't one.



More polyrhythm than an orgy in a Tourette clinic.


That's a great line. Actually pretty good...although I think you just gave me epilepsy.
 
Just replaced the alternator in my car, it's charging perfectly now. Trouble is, the new alternator is running extremely hot. Way too hot to touch.
Any bush mechanics on here have any ideas?

Granted, I never touched my old alternator after 10 minutes of driving, but this seems insane. Could it be a bad ground? I would have thought if the ground was bad, it wouldn't be charging the batteries well?

Could be a short somewhere as it being hot just means it's working far too hard, but that it's not dropping voltage and still charging the battery, you would think it has to be wiring or electrical orientated. Maybe an internal diode fail and others are compensating?

Edit: I suppose you've already checked for corrosion and such around those connections that might be causing such.

Too hot after how long? If you've gone for a long drive and the whole engine is hot it's probably not a massive issue. If it's glowing after 10 minutes it sounds NQR. If it's new cheap part some are just crap and come faulty so perhaps a bearing or something were overtightened. It's a mini generator so the belt is puling magnet around inside a tube of copper wire that generates power back to the battery. If it has faulty bearings or it's been put together too tight it might be causing extra friction.

Could maybe try wrapping some Lettuce around it 😬 šŸ˜…

I haven't checked for corrosion yet, but tomorrow I'm gonna clean up all those connections. Apparently it's best practice to do that when you put a new alternator in, but I didn't know that until now lol.

Way too hot after 10 minutes of the engine being on.

I'm pretty sure my dual battery isolation was the cause. My 2nd battery was dead, and after I turned the car on for the first time I could hear the isolater clicking off every 20 seconds. I let it run like that for a few minutes while I tried to diagnose that issue, when I had the multimeter on the 2nd battery it would go from 9 volts, to 10 volts to 11 volts, then the isolator would kick in and the battery would run out of juice instantly.

As soon as I put my foot on the accelerator, I believe the alternator was more capable of dealing with both batteries and that stopped the isolator from switching on and off.

I reckon the heat came from those few minutes that I let the isolator turn the circuit off every 20 seconds. I did a few 45+ minute drives and it's still hot, but it's a much more reasonable temperature now.

As with anything when you're plugging something new into something old, you clean that bastard as best you can so that the pairing doesn't have crap between it that might make everything a bit shit. Otherwise known as cleanliness is next to godliness regardless.

Is a good practice to get into that mindset when you have a new toy for something you have, if first instance is then "is this bitch clean?" when you plug and play you can isolate pre-existing BS from any potential error that pops up.
