Sr20 voltage loss! Help! - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

So My sr starts up at around 12 volts then as you rev it it lowers to around 11 and so on an so on. Once you drive the car it sputters and will eventually stall out without the car even moving . I replaced the alternator with the ka alternator and put new cool packs and igniter chip (it was previously not starting) so if someone could help me out here that'd be great I've been fighting this problem for a week or 2 now. It's a red top in a s14 im pretty sure all the grounds are good on it

Get a multi meter...and check things...

what is voltage at battery
what is voltage output from ALT while running
what is voltage at fuse box when running and off
etc...track that shit down.

also make sure you correctly wired the ALT. you need both the sense and dummy wires.

make sure you dont ask how to do that, because its all over the mother fucking internet

Make sure you get this FIXED! You can lose an engine with voltage fluctuating like that.
