Hey Guys 

Just got my first Z (240Z 1971) a very nice car, and after just 15 miles, I´m sold...

I discovered that my headlight and gauge light are following the revs of the motor?

Alternator issues or?

I'd tighten the belt first, then put a voltmeter on the battery leads.  Should put out 13.5 volts or better while idling.

Congratulations on your purchase.  let's see some pictures. 

Siteunseen, Thank you... I will try that.

Here is a couple of shots..

That is a sharp car!  Looks very original too, you'll have some fun with that.

Very Nice!

This is a highly recommended headlight upgrade for the 240.  I'm not much of a night driver so I can't say how much brighter but everything I've read has been positive, much brighter.  This rewires the headlights to pull straight off the battery.  Handmade by a forum member.

Other option is from Dave.  I think he was the supplier to MSA. I could be wrong.

i just ordered it myself. I rebuilt my headlight switch, but I just don't care for the heat I'm getting in my fuse box. I think I'm going to do the parking light upgrade next.

Did you get it from him direct? I'd read he was only taking MSA orders. Thanks for any heads up. Cliff

Yes, I just ordered it Friday.  He shipped it Monday.

It´s the same problem on early Porsche´s, so a relay like that seems like a good investment, Thank you guys...:-)

 

Thank you! Let us know how easy it is, that's all I've read. Really simple plug and play type.

That is an amazing looking car!  Congratulations on a great find.  You have exquisite taste in color (no bias toward Safari Gold here, none whatsoever )!

I'll add to the recommendations on the relay upgrades for the headlights and turn signals / parking lights.  Those changes will take a huge load off the fuse box and switches.  Also consider upgrading the flasher cans for the turn signals and hazard lights to newer electronic models.  The turn signal can is on the steering column, the hazard can is on the right side kick panel.

Wouldn't going all LED bulbs also take the load off the wiring harness, switches and fuse box?
