1999 V70 Na Wont Crank But Lights Come On...


98XCFxRUpR

Recommended Posts

New battery.

Getting 12.5+ volts on green ignition wire at starter when key turned.

Getting 12.5+ volts on red cable at starter.

Dash lights and headlights come on in key pos II

headlights turn off in key pow III

Took starter out and can make the motor and solenoid function by applying 12v to the terminals as described in several online starter troubleshooting guides.

What do I do next. I'm at a loss.

Thanks,

chris

I'm not sure I follow. How can I turn it over by hand? Ill try almost anything at this point. When I had the starter out I bench tested it with a weak spare battery (11.5v) and it still worked as it should...

I re checked all I did so far plus I took apart the pnp and cleaned the contacts.it looked remarkably good for 200k miles compared to my 98 sc. Maybe it was not original. I just bought this car.

Anyway, this time checking voltages I cannot get voltage on the green ignition wire to the starter. Maybe I misread it before. This is why I checked the pnp.

Without a wiring diagram I don't know what other checks happen for ignition. Pnp, ignition switch, but what else? Ive swapped "j" relays with no luck.

What else could be in the way?

I recently had some trouble starting my 99 NA, tried multiple good relays and it wouldn't start but when I pulled the relay and put batt+ straight to the line to the starter (with the key in the run position) it started right up, was the weirdest thing.

But, since you've got power on the signal wire... did you check the ground?

Thanks. I will try that.

It turns out I didn't have power on the signal (green) wire. I've rechecked and I don't see any voltage when the key is turned to the start position. Something is interfering. I downloaded some wiring diagrams and am studying them now. So far they don't tell me much.

I'm looking for the other things that I can disable to allow that voltage through to the green wire.

If you want to hotwire it like I did, pull the cover on the fuse/relay box on the driver's side strut tower, pull the grey relay, look at the diagram on the side and use a short piece of wire to hotwire the switched side with the key in position 2. That will put batt+ straight to the starter's trigger line and start the car. Your issue may be as simple as that relay itself. While you're there you can check that wire for continuity easily.
