What does this light mean? long hood
 
Low on oil?http://forums.pelicanparts.com/uploa...1617260366.jpg

Isn’t it the park brake?

pwd72s 04-01-2021 12:16 AM

Double duty light...parking break and voltage...check voltage with a multimeter. Could be an alternator problem...hard to tell at low RPM tho...

Warning...it's been a long spell without a longhood and relying on a fading memory.

Parking brake? That's interesting. I never knew that there's a light hooked up to it. It comes on periodically through out my drive today. This is my second drive. Took it to get it aligned today, on my way back, I noticed it. I don't have a parking brake, Wipers and such. Its been taken out for weight savings. If I am to drive this on the street more often (looks that way for now), it must be re-installed.

Alternator?

Thanks, keep em' coming.

What's the light for next to the key down below? I have never seen it lid up. I have had this car for 9 months but have not had a chance to monkey with it.

rusnak 04-01-2021 01:10 AM

hazard or 4-way flasher

rusnak 04-01-2021 01:11 AM

The B should indicate low brake fluid. The G should indicate low voltage.

rusnak 04-01-2021 01:15 AM

The top light I think on my '70 914-6 is a green colored light that indicates low oil pressure. But I'd have to go check it.

unclebilly 04-01-2021 01:16 AM

Also that R tach is crooked, you need to straighten it...

Hoodlums!

LEAKYSEALS951 04-01-2021 04:09 AM

The switch below the hazard button on the dash. That's the NOS button, right?

RNajarian 04-01-2021 04:40 AM

In my ‘75 it indicates handbrake is on. The “G” light below is low voltage.

look 171 04-01-2021 10:59 AM

Sounds like I gotta find those wires for the hand brake.

daepp 04-01-2021 11:05 AM

Weird - I thought it was a double duty Parking Brake and Charging Light.

Thinking about it, you're probably right...I recall the alternator warning light flickering at a low brightness level with the car idling. Just no longer sure of the location. Generally, loved the gauges on my old 911S other than wishing Porsche had somehow installed a volts gauge.

Also a factor is that Porsche used different standard gauge set ups depending on the model, although "S" gauges were an option for T's and E's...

look 171 04-01-2021 11:13 AM

Charging light? From alternator? It comes on and of as I drive, sometimes glowing bright red, sometimes its just dimly lit most times, its off.

pwd72s 04-01-2021 11:16 AM

Also, looks like an aftermarket or altered tach to me...goes beyond the revs range of an original T, E, or S. S had the highest redline at 7,300.

LEAKYSEALS951 04-01-2021 11:16 AM

I googled 1969/1970 porsche 911 owners manual pdf, you might try for your specific year.

Manual page 17/ pdf page 14

osidak 04-01-2021 11:23 AM

on my SC that is the green light of death..... If it comes on while driving - shut down and check fan belt

rusnak 04-01-2021 11:27 AM

^ OK, so that is just like my 914-6, which has a "T" motor in it.

But the OP's setup looks different.

Its a 10,000 rpm tach. Newly rebuilt along with the speedo.

look 171 04-01-2021 11:33 AM

Its a track/street car. I bought an unfinished project. I had the interior done and painted the car. Its a freshly rebuilt engine and short geared transmission (came with the purchased with built specs). I have to do some digging because there's a loose wire that keeps the gauges from working 100% of the time.

Walter_Middie 04-01-2021 12:20 PM

On my car (1975) the "B" light is on for both parking brake and there is a switch on the master cylinder to show a fault in the braking system. You can see the switch on the master cylinder here:

Sorry guys

I sure wish there was a forum, or sub-forum on this site, where I could find an answer to this question..

yes, on some MYs it is a triple fault light

fintstone 04-02-2021 03:55 PM

That is the parking brake light. The one at the bottom of the gauge is for the alternator.

Thanks.

Looked and did some digging this morning. No wire from parking brake. Its been yanked out, only the handle is mounted there to keep the open hole shut. Corner balanced and aligned at 2214 lbs with 12 gal of fuel.:D I am puzzled how this light is lit up without any wired from the parking brake area? :confused:

fintstone 04-02-2021 04:31 PM

Pretty easy to swap a wire on the back of those gauges. Does the alt light come on? Are the gauge illumination lights on?

thor66 04-02-2021 04:31 PM

see above - on some MYs it also is a warning re the brake fluid in the reservoir

check it - that switch might fail so the light never comes on, but you need to run it down

again as above, on some MYs the light tells you about the alt. or the VR - there is also an upgrade re putting a resistor in the circuit form some MYs

I never noticed the alt light come on before. never turned on the lights so will check. It just sat after all the work got done and the BLM riot started so I didn't want to chance it driving it around because I don't trust and don't know what's waiting for me at the off ramp. Now that I have some time, I am going to play with it a bit.

thor66 04-02-2021 04:35 PM

Good, but after 45 pico-secs. i realized it may fail to never light up

thor66 04-02-2021 04:37 PM

I see longhood but not your MY??

Zeke 04-02-2021 04:59 PM

Bad ground wires and terminals on German cars makes lights do weird things. Disconnect the ground from the taillight housing and see what I mean. Voltage has to go somewhere.

No, that is incorrect

I'm guessing the OP is asking about the illuminated large red light..

Which is the Alternator warning light,

The bottom light in that gauge is the handbrake.

Apologies, my printer/scanner recently went kaput and I haven't replaced it, so pics

From a '71T manual which came with the S gauge package..

Not sure if you are being facetious with this comment.

I think his gauge is different than the one in your ‘71 owners manual.

If you look at his photo the top light has a B under it (handbrake/fluid) and the bottom light has a G (Generator).

rusnak 04-02-2021 05:51 PM

^ he's enforcing track limits, but on an on-line forum.

RNajarian 04-02-2021 05:54 PM

Here is a link from Pelican that answers his question.

And even that link /picture doesn't match the picture the OP provided..

Who has eve seen a flickering brake warning light

RWebb 04-02-2021 06:56 PM

big red button light is likely Emerg. Flashers

toggle switch under dash says car has been messed with...

intermittent light on while driving could be bad gnds, bad wire rubbing, of diodes failing in voltage regulator

silver button gauge says longhood but does not say which year or if it is the right year gauge for the car...

I know the tach electricals changed about '70/71 but not what else changed then

- color wiring diagrams are on here somewhere, so the fix is just a matter of time & effort
