1967 Gauge Panel

[RiverPatrol]

I was just looking at the service bulletin from March 1966 and it talks about the dash voltage regulator and itis also shown in the 1966 wiring diagram at the 5 o'clock position in orientation to the combo gauge on the diagram. I did not see anything under my dash on my 67. I wonder if there is something inline on the harness.

It was never inline on the harness. I think the service bulletin was talking in concept, that when they actually implemented the regulator it was located on the firewall. I've found that changes mentioned in the service bulletins took place months later.

Since all three of the ignition wires are tied together I would imagine the I don't have regulator as only the water and fuel went through the regulator.

But you don't know whether the replacement cluster used the regulator. You'll know once you get it all hooked up.

I sent a message to Scott to see if he knew the VIN for his Patrol, hopefully he will recall. Had I gotten the correct wiring harness back when I bought it from him I would not be having this question, but I got a datsun roadster dash wiring. I always thought it looked a little off but when I bought it a few years ago I did not really have anything to compare it to so just assumed it was the correct part. It is now on ebay looking for a new home.

My truck definitely does not have a regulator. Reading through the bulletins you have posted I looks like internally there might be some differences but not really interested in taking the gauges apart.

Heres the regulator with the wires connected.

RiverPatrol and RDarnell,
This is a thread of really import information and deserves close study. If the Patrol dashes were NOT replaced before now, meaning the model year of the Patrols are accurate for the dashes then Nissan clearly had no precise year for the switch from old style to new style gauges that utilize a voltage regulator. My 66 doesn't have a voltage regulator, which dictates the connections, but it seems some 66 models did. Furthermore, my 66 speedo operated on an early style speedo cable.

River warned me the 66 was a transition year but I think the transition was not limited to 66 based on this comparison and study.

My advice, based on my experience with the 66 is ...if you have a choice avoid the 66 year model ...for the door star gear misfit/gear misalignment/early failure if nothing else.

Patrolling again soon,

I remember seeing that relay on my 1969 now, with the flasher mounted next to it instead of between the gauges.

My 1967 has the same poor 2 year design as you 1966 doors. I had hoped to solve the problem with a pair of body mount strikers that I found listed in Thailand. They did not solve the problem. I will probably do a conversion later and use the bear claw style that is popular on street rods. Kits can be found on Ebay but would still have to make the handles work.

From facebook post it looks like Paul Wilcox has #07904 1967 and his has all three ignition wires tied together like mine. I wonder if some of the changes in the service bulletins did not occur until they used up prior stock. I also wonder that since the L market was not so large that our changes lagged behind.

The voltage regulator change might have happened at the same time that the gauge connections changed to spade connectors and the bottom of the dash left open. maybe some late 1967's got those changes?

Don't forget the crappy driver's seat rails that lose the ball bearings on the '66 and '67 too. Fortunately those can be fixed though.

Paul is pdub here on the forum. I had a '67 Patrol that was ID# 10550 that had the regulator. Looking at the Registry, there is a huge mix in the transition from '66 to '67. Both your '67 and Paul's have ID numbers that are earlier than two of the '66s that I have. So, it's impossible to say what changes were made when.

Well then....we have a mystery wrapped in an enigma. Which gives some of us a stigma.
Patrolling for parts,

Do you recall if the bottom of the dash was open like later models or enclosed like earlier. Also did you ever see the back side of gauges, I wonder if it had ring or spade connectors?

fortunately once my seat is set I will probably never move it!

[RiverPatrol]

The bottom of the dash was enclosed until the '68 model changes - SO much easier to work on the dash electrical that way. The '67 that I had the gauges had spade connectors, it also had the gauge regulator.

The problem with the seat rails is that once the ball bearings fall out they come apart in two pieces. You can't even adjust the seat or leave it in one position, they are just two pieces of metal with nothing to keep them together. There is an easy fix though, I've fixed 3 sets of them. It just requires determining and then finding the correct size ball bearings and persuading them back into place.

I just looked at my pink slip. it does state first sold 00/00/66 but next to that says year model 67.
