Ok, so I got my car registered on Monday, finally, and it passed it's inspection first go with all but the window washer motor (front) not working.

After taking it for it's first decent drive (and having an exhaust mount break) all seemed to be ok, still needs some tlc but nothing major.

Day 2 and all is well for the drive to tafe, but when I left to come home car was hard to start, wouldn't idle at all, and all the dash lights were staying on (reds) charge, fuel, brake ect. Volts gauge is showing normal reading and car will run if you keep the rev's up it. No blown fuses not sure where I should start probing......any ideas?

Cheers Dan

Sounds like an alternator issue mate. When mine blew up my dash lit up like a christmas tree. Found a replacement at the wreckers off another l series motor for cheap and has been fine for almost 2 years.

Thank you sir,

I was hoping that was the case as I haven't had time to look at it yet, but really don't want to be chasing a short somewhere in the loom/s. Would consider an engine conversion before doing that :thumbsup:

Can I use an alternator off any l series motor l16,l18,l20?

As far as i know yes. But someone please correct me if im wrong.

Another thing that happened to me is i kept driving it till the battery went flat so probably avoid doing that if possible lol. It's a pain in the ass.

Well I got my alternator reco'ed but the problem persisted, turned out to be a dodgy fusible link (alternator bearings where shagged anyway)

Dose anybody know what the correct rating for the 4 fusible links is(red, 2 x green, brown). As well as the main link from battery "+" terminal?

Considering changing to a newer style fusible link like some of the 240z guys are doing.

Cheers Dan

There are a few makes of alternator for the L series (hitachi and bosch from memory). While all the L series alternators physically fit the C210, some have a single pin plug in the back, and others use a twin pin plug. The plug can be removed and replaced, but the plug and bushes are all in the one assembly, and often worn bushes are causing crappy charging in the first place.

Unless its a dodgy fusible link, blown diodes, or clapped out bearings, of course.

Again, from memory, if you use the single plug system it still actually works, but you get an annoying warning light on the dash.

Hi i think i can help you with your fusible link ratings.. ""brown link"" 0.3. ""green link 0.5. ""red link 0.85. ""black link 1.25.

Also i would check the voltage regulator, if you still have the old points system, convert to a electronic one

this only applies if you have a 50amp alternator, the efi skyline had a 60amp alternator with inbuilt regulator.

Cheers Mario.

      Wife wanted basket things in the wardrobe in our temporary house. Thought about ripping our the wardrobe and fitting the entire IKEA set, but it's a temporary house and we want to move in a few years. So IKEA advertises this as a 50cm unit, however the actually basket and rails measure 46cm wide. Only issue was depth, IKEA stuff is quite deep, where as the builder special junk is super shallow at less than 40cm. Send it, chopped the rails, then offset the mounting holes, job done, happy wife, less shit scattered all over the bedroom. Did the same to the other side too. Also drove the Skyline shit box today, dropped off oil at Supercheap Auto. I didn't realise they only now take max 2x bottles per visit. I visited 2x Supercheap Autos.

      Strange issue RB25DET wont start

      I've seen similar actually in my situation. You never know what tables are attempted to be used when the car thinks it's -99C or +200C. The fail state is not usually that extreme but you know what I mean - it was in my case though! This is where being able to read all the sensors is useful cause you see this stuff really quickly.

      The above is very important. However as long as you keep timing relatively low, it's plausible to make your own knock ears and plausible to learn to tune with a modern ECU that can do wideband O2 correction like a boost controller. I mean if you only have one viable road to even drive the car on, learning to tinker to this level may be worth doing given you can't do much else with the car...?

      I find the fact that the rear plate has to be bent inwards at the rear not so bad: but the front is just awful: It's like come on. (these are my very old, now retired/turned in plates) TBH it is a lot of money to fix a minor issue, the fact I said "I'll never really spend the money on doing this" is why people ended up buying them as a gift for a 'car guy' who can be hard to shop for.. for car guy things.

      I just bent the ends of my premo plates. It even went through Regency like that after the engine conversion and the inspector (a great bloke!) just squinted his eyes and said "I didn't see that". Plates, and how they look, are just something that have zero importance to me.
