Thread: SR in limp mode

So to start off I was driving an noticed my battery light, so I took readings on the alternator and it's only making 11.5v. I was able to get home with no issues. 2 weeks go by and I don't drive it, just go outside and let it idle. I decided to rev it up one time and noticed it would only rev up to 2-2500rpm. At the same moment my tach dropped off and read 0rpm no matter what. I replace the alternator thinking maybe it had something to do with the tach and putting it into limp mode. Well it's replaced and the car is still in limp and i still don't have a tach reading. I've reset the ECU multiple times. The set up is a GTIR cluster, bluebird sr20, MAP ECU on an N/A ECU, MSD Digital SCI ignition control w/ blaster coil. Any ideas would be helpful, I've checked everything I can think of.

it is your meter fuse in the fuse panel at your left knee

the dummy light for the battery completes the circut for charging and if the fuse is blown for the meters then there is no dummy light. low battery will keep it from revving also

I'll triple check it. I put my multimeter on every fuse and everything checked out good. I'll let you know what I find.

Replaced the meter fuse and nothing changed.
