hi guys

my brakelight on the stock s2 wing blew so i've decided to pull it apart to see if i can repair it/use the LEDs for something else.

it wasnt actually very hard to dismantle, just needing a little tlc with a small flathead screwdriver in between the black and red bits. be careful cos its easy to chip/crack the red part. its lined with a little glue that you need to crack is all. be patient

the red part just lifts off and underneath is a long pcb with lots of leds screwed to the black plastic. there is also one resistor on top (same side as leds) and 12 underneath (See bottom pic). its set up so that there are 48 leds set in 12 parallell groups of 4 leds each, with one resistor per group. the resistor on top is set in series with each of these groups

now when i pulled the red part off, it was pretty obvious which bit had failed. the resistor on top had been crisped (see pic). now my question is - does any one have a clue as to the value of this resistor? it looks like a very simple fix if it wasnt for this missing info. if its available in fast can someone pls look it up?

this is mainly for my own info but i'll write up the rest when i get an answer. mebbe it can then be moved into the diy section? oh and better pics will be up tomorrow

Just opened mine up and low-and-behold, mine had the same resistor blow-out but it has no identifiable markings (a small pile of green dust).

Does anyone know what resistor goes there?

BTW - When these WERE available, they were $500. I found 1 at a wreckers for $250...if we can figure this out, it'll be worth making it a sticky.

the resistor blew because you were riding the brakes. brakes just slow you down, what are you using them for?

sorry, don't have anything more constructive to add. I could pull apart my car and find out what value of resistor is in the tail light but I'd probably put a screwdriver through it in my current state :(

DONE!!!

Went to Jaycar and we did some testing. The guy figured that that particular resistor was probably a fusible resistor, designed to be the first thing to blow (rather than your LED's).

Anyway, bought the resistor's designated 'RR0524'. These are a 10 ohm resistor. For a brighter light, use 2 of these in parrallel or a single 5 ohm resistor. Unfortunately, I don't have anything to compare how bright the 10 ohm resisitor is as they havent worked since I got the car.

So there you go - $500 for a brand new one, $250 for a secondhand one, or 0.38c to repair your own....

      Rb25det Belts Change

      By joshuaho96 · Posted

      Everything I found online said never use it because it'll dramatically reduce belt lifespan.  No, but I have seen excessive v-belt tension cause the audible bearing noise from excessive radial load in things like alternators. So don't overdo it. Ideally you set it to manufacturer spec using a proper belt tension guage. I tried the "clicker" type gauges but those cheap things are trash. They read way too low even when you're careful.

      This is kind of where I've ended up for the most part. It's easier for me, easier for shops that don't have to deal with my weird criteria/picky standards, etc.

      Will do. Suprised if it's not the starter motor considering it's 30 years old. Will get a volt meter though. Battery is close to new.   Cheers for your help, always appreciated.

      This almost never happens these days. No. Clean your battery terminals and make sure they are tight. Use sandpaper on a dowel if you have to, to get oxidation off the inside of the terminals, particularly on the -ve. Check the earth cable from battery post to chassis ground and engine ground. Make sure the contact surfaces are clean - including the threads on the bolts that anchor them - because that's where a lot of the contact occurs. Wire wheel on a drill is a good thing for this. Make sure the crimps on those cables are all sound. Assuming none of that causes an improvement: Check the battery voltage after it has been resting for a while. If it's at the lower end of the range, put it on charge for a while, then see if it will crank better.

      I just checked my belt, it wasn't super loose but I could bend it past 90 degrees a small amount so I tightened it up and for the first time ever my car didn't crank first time, had to crank it again lol. Don't know if that was because I tightened the belt or if it's my starter motor going out (been having slow starts for some time). Coulda also been when I was recording I didn't crank the key properly and it didn't save the recording lol.   Is that a thing if you overtighten a belt it struggles to start?
