Headunit Restarts Itself

[Charles89]

Hey guys,

It only started happening today, when I'm at the lights and I ride the clutch a little, sometimes my headunit just restarts itself and continues playing. Is it something that is battery related?

Another thing that I noticed is, when I was driving home tonight, when I stopped at the lights indicating to turn, all my interior lights just blinks at the same time as my indicators, and I think my headlight as well (slightly).

Appreciate it if anyone can help me out

check your alternator.

check your alternator.

How do I do that? (sorry if it's a dumb question )

Also, every morning or whenever I haven't driven for a few hours, I start the car, it takes less than 1 sec to start up. But if I do a short trip to the shops and start the car again within 10mins or so, it will take a few secs to start it.

Is that because of the alternator?

Thanks Chris!!

yep sounds like a bad/problem charging system , but could be a bad battery(low current holding or low water if its a wet system) or bad ground/positive terminals loose corroded ?

some auto shops have free testing on batteries/alternators,

buy a cheap digital volt meter for like 10 bucks to check if your car is charging or not ? jaycar, supercheap or ?

needs to be around 12v with engine off

roughly 13.8-14.4v when running

if all good turn on your lights, with engine on and retest voltage, is it getting lower and lower or stable ?

post up the results

and clean and tighten the terminals (post cleaners/wire brush ) is only a couple bucks

if you have a small jap battery , expect it to be dead ...lol , good reason to update your battery and terminals to Aussie standards

most of the time it's a bad terminal, R31 did that and the positive terminal was cracked on the underside, causing resets and low voltage
