Battery Dead, Lights Flashing

Neighbour came knocking on the door tonight, says the lights on the car are doing weird things. I go out, and they are, rear lights and at the front, flashing between high beam and the fogs .... not bright, just dim like there's not much power. And there's not either, not enough power to open the doors by remote, or turn over the engine. So I've disconnected the battery, but now what?

I've looked at this post http://www.skylinesaustralia.com/forums/topic/343588-possessed-lights/page__p__5540346__hl__battery__fromsearch__1#entry5540346

but today has been one of the driest, sunniest days here in Melb for a long time, and there's not even a hint of moisture in the battery compartment. I didn't have the car today, my wife was using it, but it doesn't sound like she was doing anything unusual with it, certainly been no warning lights on recently.

I'm presuming it will go again with a jump start, once the RACV get here, but any ideas as to the cause? It's an '04 300GT sedan.

Cheers,

Richard

Thanks Chris, will do.

Is battery death in these always that sudden, or should there have been other signs?

there is not a science to it.

IF you are lucky the car will be slow to start otherwise it will simply die. average life of a battery is 2-3 years at best. if in doubt - change it.

So when the car comes back to life it 'knows' where the windows are. You know that little automatic adjustment your car does when the door closes? Yeah you need to reset that.

Put window down, put window up and hold the up button for three seconds at the top, put the window back down. You should be good.

Just curious,

i changed my battery last week and read you needed to make sure the windows were all the way down before disconnecting...why?

So that process of "put window down, put window up and hold the up button for three seconds at the top, put the window back down" is after disconnecting and connecting it back?

Hmmm cant say i did that exact procedure,

but as far as i can tell windows go up/down fine and still do that lil kick at the end.

Well I got the RACV to jump start it this morning anyway. Seems like the fog lights had been switched on accidentally, which obviously did the battery draining trick. Guy said the battery was still very healthy, so I'll just leave it and keep an eye on it for now.

      So.....wire it up appropriately. You can't use the resister pack with those injectors anyway.

      ahh okay cheers, i was thinking of just going for the m073, think m079 would be way too overkill considering they are same size.

      My first car was a HG. I'm very familiar with them. A mild cam upgrade is a good idea. The 186 is a very flexible engine - meaning it has good torque from down low. You can give up a little torque down low for quite a lot more excitement in the mid range, and a bit more up top - but they are not exactly a rev monster. You need to upgrade valve springs at the minimum. For a bigger cam, you'd want to make sure it wasn't still running the original fibre cam gear. That would be unlikely, given that most of them shat themselves in the 70s and 80s, but still within the realms of possibility. Metal cam gear required. Carbies are a huge issue. The classic upgrade was always a Holley 350, which works, but is usually pretty bad for fuel consumption. The 186S had a 2 barrel Stromberg on it that was very similar to the one on the 253, and is a reasonable thing if you can find one, and find someone to help you get it set up (which is the same issue with setting up a 350 to work nice). The more classic upgrade was twin sidedraught CD type carbs, or triples of same, or triple Webers. The XU-1 triple Webers being the best example. You can still buy all this stuff new, I think, but it's a lot of coin to drop. And then the people able to set them up are getting fewer and further in between. There's still some, but it used to be everyone's** dad and uncle could do it. **Not everyone's! But a lot. All in all, I wouldn't get too carried away with the engine. Anything you do to it without a full rebuild for power and revs will only make it slightly faster. I am all in favour of a complete teardown rebuild, with nice rods and pistons, 10 or 10.5:1 compression, and a clean port job with at least a big enough cam to run 98 with that compression, if not bigger. And if I did that to a dirty old red motor, I'd want to inject it too, which I'd struggle to fight against the devil on my shoulder that would argue for ITBs and trumpets. But the bills would start to mount up, and it will still never make stupid power. OK, a few people still know how to build absolutely mental red motors, courtesy of the work that went into HQ racing and modern knowledge being applied. But even a 300HP red motor is no match for an RB20 with a TD06. So you have to decide what it's worth to you. I'd just put a set of 6>2>1 extractors, a 2.5" exhaust and an electronic ignition conversion/dizzy on it and just run the old girl like the fairly slow old girl that she really is.
