Light has come up on my dash this morning. RH side of cluster, bottom row, on the very left. It looks like a house with long windows kind of?? To the left of the exhaust warning light and oil light. Might get some pics up tonight if no one can help out.

Low water in your radiator over flow bottle or somethinng along those lines, i overheated mine once and that warning came up, filled overflow bottle back up and didn't have any other issues

Is anyone elses battery light on constantly?  I've always got heaps of charge to crank it over and I left it standing for a couple of months and it was fine

My bet would be that your alternator will give way in couple of weeks time. Thats what happened with mine, I believe boof has gone through a few too.

yerp word to that, 4 in a bout 3 months or something stupid!! it results from the regulater being to slow to regulate so kills the alternators pretty quickly i beleive!!

Coolness. The light went off straight away after restarting this morning. Just got home from a 30 min drive back from g/f's house and the light came on for a while, then went out. I checked coolant today and it was fine, but will top up over flow bottle tomorrow.

Hmm... the battery light has been on since I got the car and I've been driving it daily for 12,000km in 6 or 7 months.

You checked that all your wiring to the alternator is connected?? Sounds like some dodgy wiring going on there somewhere maybe, i know when my alternators are going to die, cause all my warning lights on my dash come on, door lights the works!! Silly dr's

The reason that all the dash lights come up is the bulb-check sequence. There is a relay hooked up to the alternator & battery that is only energised when the alternator isn't charging. Hence when your alternator dies, not only do you get the charge light illuminated - all the other lamps come up too (except the high beam & cat converter temp from memory).

The original almp in question is the low coolant overflow warning lamp. Chances are that if yours doesn't work the bulb is gone - I replaced about 4 when I got my DR to get them all working.

The bulb-check sequence reveals all! :D

      S1 Autech 260RS Wiring Diagrams

      By ARB26 · Posted

      Newbie here, proud owner of an Autech 260RS. I'm on the hunt for wiring diagrams specific to the 260RS, particularly S1. I've ran my eyes through R33, R34 Diagrams, there are some similarities, however continue to find incorrect wire colours and pins on connectors in the 33,34 diagrams.   I was hoping someone could point me in the right direction? I'd be happy to pay for the originals in Japanese. I can translate them, at least they would be accurate.   Any help please would be greatly appreciated, never heard an RB26DETT before let alone driven one, and I've got a spaghetti monster of goodness to sort out.   Cheers Benny

      Tein Circuit Master- rebuild worth it?

      By QB6SAGR · Posted

      Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻
