Re: Grounding question



Mike, you can check your factory gauges with two AA batteries connected in series.  The + side goes to gauge terminal marked A and the - side goes to terminal S.  Except for the ammeter, because its workings are entirely different.   This test should give you a reading around half scale or a bit more and won't damage the gauges.  To test the ammeter, apply +12 volts to one terminal (doesn't matter which one) and ground the other briefly.  The meter should peg in one direction (again, doesn't matter which).  Now, reverse those connections and the meter should peg in the other direction.  Don't leave the ammeter connected, just a brief connection (say 1/2 second or so - just long enough to see the meter peg).  Another test that's quick and easy is to check the meters for shorts.  All the gauges should show "about" 20 ohms.  These tests only check that the meters are functional, they do not guarantee accuracy.

That lead marked gauge power will be 12 volts. and will kill your factory gauges!!!  You need to connect that wire to the Instrument Voltage Regulator terminal marked "I".  With the cluster's ground buss connected to ground  and the gauge power wire connected you can briefly ground the "S" terminals of your gas and temp gauges.  The meters should go to full scale in a second or so.  Don't leave that terminal grounded for more than a few seconds or you may damage the gauge.  If you're using your trickle charger negative wire to ground the cluster, this may not work, because the gauges need a certain amount of current to operate.

There are folks doing business on the net who can clean and calibrate your gauges and restore the meter scales to like new condition. 
Check the Vendor section linked from the website homepage.

Navigating the wiring diagrams to get the right one is a little tricky.  At the bottom of each page, there is a model designation.  Your Belv. II with V-8 engine is model AR-2
And, of course, the factory wiring diagrams won't help with the EZWiring.  They show how it was designed and that helps to figure out how to use aftermarket wiring.

All for now!

Thanks for the response Bob. I'm actually using a trickle charger connected to the battery cables just to see if I'm getting things hooked up correctly. I have all my switches hooked up and working and now I'm just trying to get the instruments connected and working so I can start to button things up and get the fresh rebuilt 361 fired up for the first time. I still have a long way to go and a few bugs to iron out but I think I'm on the right track. Thanks for the tip on adding the ground wire, I'll do that.
I'm not planning on adding any high power add on's to the car, I'm trying to stay as stock as possible. I have the stock Alt. The wiring kit has one lead marked gauge power and is shown in the kit diagram as going to one side of each gauge for power and then the other side is ground. This diagram is shown with a volt meter, am I better off going with a volt meter or should I stay with the stock ammeter, it seemed to work ok before I took everything apart. The ammeter is hooked up independently to the started solenoid and alt. isn't it?
I'll take a closer look at the FSM you sent.
Any other suggestions or guidance would be appreciated.

The instrument cluster in our Mopars is SUPPOSED to be grounded through the mounting screws to the dash frame.  If you're working on the cluster using the car to power it, you need a wire from the cluster ground to a good solid body ground.  It's a good idea to add that wire to the stock cluster anyway, otherwise the cluster may become intermittent.

Here is a complete '65 Plymouth Factory Service Manual: http://apicdn.viglink.com/api/click?format=go&key=508e022f256315a50e8e5af8c001704f&loc=http%3A%2F%2Fwww.forabodiesonly.com%2Fmopar%2Fshowthread.php%3Ft%3D244981&out=https%3A%2F%2Fwww.dropbox.com%2Fs%2Fupks33txhbe9tjw%2F1965%2520Plymouth%2520Service%2520Manual.pdf&ref=http%3A%2F%2Fwww.forabodiesonly.com%2Fmopar%2Fforumdisplay.php%3Ff%3D35 wrote:
I think you are asking how the instrument cluster on a 1965 Plymouth "B" is grounded?  Is that right? 

Also, while you have the cluster out it is a good time to consider having that ammeter gauge converted to a dc gauge. 

Thanks,

Hello all. I'm trying to hook up my instrument panel during the rewiring
process. I'm using the EZwire kit. I have everything connected but I'm not
sure about grounding the panel. Is it grounded through the mounting screws
to the dash? I'm running power through it but I'm only seeing any current
using a test light that's grounded to the dash. I have the instrument power
connected to one side of the temp gauge and one side of the oil pressure
warning light and gas gauge. I know I need to run power through the ammeter
but that can come later correct? Any help or suggestions would be
appreciated.
