Tachometer NOT working

UPDATE: Just delete this thread, amazed how no one can help me on a legit question that I layed out ALL my issues and I was looking for the ‘experts’ advice on what direction to even go to. I didn’t expect spoon fed answers, but neither did I not expect any answers. Thanks guys, really.

I think its the distributor. Test that wire with a volt meter, it may not be working. Are you absolutely sure its wired correctly?

Yah because no wiring changed since my LS swap, and all I did was an LSV swap and add this ‘new’ VTEC distributor. I’ll see if I can find a volt meter but if not how certain are you it’s the distributor?

Very. If its the only thing associated with the tach that you changed, and your tach suddenly stopped working, odds are pretty good thats the problem.

Ok now to find someone with a distributor I can test or buy one which sucks with the weekend. Thank you, I’ll keep this thread updated as I make progress.

Cool. Hope you solve it.

Tried a new distributor, same issue. I can see the RPMs on my Hondata, so I’m gonna trace the wire from the cluster to the ECU and see what’s up.

if you can see it on the hondata and not the tac, defiantly sounds like a break in the wire some where. ohm it out and see what you get?

Dont have a volt meter or ohm meter. And my wires are a bitch to trace. I’m thinking if you guys can tell me what pin on the cluster connector is for the tach from the ecu, and what wire is on the ecu for the tach I can cut them off and splice off that instead of undoing my wire mess. Thoughts?

Or I can tap off the blue line at the distributor, but where does it go on a stock tach? Do I run it from the distributor to the connector B, pin 4? And if so how will my ECU get the RPM signal? Can I just split that blue wire off the distributor and keep one going to the harness so the ECU can see the RPMs, and then another wire to hit the B4 pin so the tach moves? Last day I can really work on it full time since I work M-F and Weds I have to get it to Evans.

Can anyone with electrical experience chime in as to the best way to fix my situation? Please?

Bump for an answer as to what pin on the cluster connector is for the tach, and what pin on a P28 ECU is for the tach so I can run a direct wire.

Is the A21 pin the correct location I should be splicing from on the P28 ECU and run it to the B4 pin on the connector behind the cluster to fix this?

A little help would be nice… :whisper:
