Added Tach, now gauges are screwed up!

Hi All,

I have a non-JX 88.5 Suzuki Samurai (square dash vents). I wanted to add a Tach, so I purchased an instrument cluster from a 88.5 JX model at a Junkyard. I swapped the two clusters, and the Tach, Speedo, idiot lights, and turn indicators all work fine.

The Problem is that the Fuel and Temp gauges now read way off. As soon as I turn on the Sammy the Fuel guage moves to full, irregardless of actual fuel level. The temp guage stays in the cold area until the engine starts to warm, and then it shoots way off the hot end of the scale. Since my engine hasn't melted, this is also inaccurate.

I Love my new Tach, but need the other guages. I tried swapping the Fuel/Temp guage from the original cluster, but they don't fit at all. The cluster is not returnable.

Any help would be greatly appreciated!!

Re: Added Tach, now gauges are screwed up!

i have not seen this happen before try checking for
corrosion in plugs on new dash then make sure of grounds
for guages. my 88 is a jx and came with a tach but have
swapped dashes on others with no problems-but i use
dielectric grease on reassembly on plug-ins. oldzuki

I put a 88.5 instrument cluster into a 92 and had to rewire the instument cluster. The printed circuit is not the same on both and the gauges were the most different. Trace the printed circuit back to the plug-ins and compare the two clusters. Also make sure that the gauges have the same polarity as the old ones.

Re: Added Tach, now gauges are screwed up!

Sounds like a bad connection that grounds both of those circuits jointly... Get a wiring diagram and look for the ground that completes both of those circuits. The conversion should work properly if all was hooked up correctly... I have heard that the harnesses and clusters are different but you should be swapping the entire harness & dash as a unit and simply plugging it in. The tach feed is factory installed in all firewall harnesses...

I thought you could just swap them out... I took one out of an 88 to sell on ebay. And advertised as such I hope its just a connection problem because they are already bidding on the one I have for sale...

I believe your information is correct. I installed a tach cluster in my 86. It was a plug in & go; everything works.

Re: Added Tach, now gauges are screwed up!

The JX cluster with the tach is wired the same as the others (at least for the carbureted Zuks). I've swapped the round vent dash type JX for a round vent non-JX type before with no problems. A bad ground connection will cause both the fuel and temperature gauge to behave as you described. I've never been able to find a square dash pod with a tach, but would like to find one for a '93 fuel injected model if anyone has one.
