Hi Tamo,

 

Actually I think the drawings in the FSM for the alternator section are pretty good.

 

Are you having a problem with yours?

Thanks Captain.

 

Now, I'm working on the IGN relay.

 

I saw photo of new IGN relay.

part number (PN: 25230-89958) and cost $60 or more....

But don't see schematic for easy wiring.

So, I draw one.

Do you think this is correct wiring?

 

Thanks,

I have made a few of these. I don't think $60 is that high considering the cost of parts and labor to wire the base. I think I was charging $45 shipped in the US.

I end up ammeter / voltmeter swap like this with CS144 Altnator.  I still have 3 issues. I can't figure out what is wrong. My battery and alternator are brand new.

  1. Charge warning lamp won't turn on.
  2. Voltmeter is not work.
  3. This Alternator is not charging the battery. When running engine, the battery shows around 12.20V. It should showsaround 14.xxV

Here is the original Ammeter schematic for '75 280z.

Here is '77 280z Voltmeter schematic.

Could someone advise me?

Thanks in advance.

I got help at Hybrid Z site to figure out issues.

First of all, the charge warning lamp was out.

Then, voltmeter connection was wrong. I need to connect to the 12V constant.

Here is the final schematic.

Tamo,  Just wanted to say that I'm glad you got to the root of the problem and let you know that I read your post and wanted to help, but I know nothing about the CS144. I was hoping someone else here would chime in.

So I'm just happy you got the help you needed, even if it wasn't from here.   :beer:

What power window unit did you go with or was it a kit with the locks to provide the “roll up and lock” feature on the fob?

That is a lot of nice modernization.

What's going on with the red light and the RPM?
