yes, post pict of the carb and the air filter assembly with the various vacuum hoses, the later air filter enclosure need some vacuum to keep a flapper opened, otherwise it will run rich.yuza wrote:Oh, and yes he replaced the carb with a stock one from US, I might post a picture tomorrow if it helps
In my case, I have a bench power supply which I used to verify function, but for most people it's probably easier in the vehicle for a so you have a source of 12 VDC. If doing it in the vehicle you will need to connect the red and yellow leads that went to the ammeter together as with that open there will be no voltage to the dash. You're going to need a multimeter and two jumper wires, as for the multimeter all you really need is a cheap analog one that can measure resistance and voltage, I think analog works best in this case. First make sure that you have continuity (low resistance) between the metal case of the temp gauge and the the ground pin. Reference page 1L-44 of the 1979 TSM for the cluster pinouts/connections. On the rear of the pcb you will see the three terminals of the temp gauge, each of which is labeled. S is input from the temp sender, A is 5V, I is ignition (12V). With 12V at terminal I and a good ground connection (you can use jumpers on pin E of the round connector for 12V, and the black wire on the rectangular connector for ground) you should see 5V at terminal A. There is a slight cavet though. The CVR is an electromechanical regulator; when it's powered a set of points vibrate to give an approximate 5V, it's far from a clean 5 VDC so using a digital meter on DC can give you some funny readings, this is why I suggest an analog meter (I had a brain fart when testing mine and never thought to try was using the AC setting to get a RMS value which might work well though). As long as you see a few volts even if in pulses, your CVR is likely fine (when I looked at mine my old Micronta meter showed regular pulses going from 4-6 volts when set to DC, your mileage may vary).yuza wrote:How can I test if my CVR works or not?
Or, if it is just a bad ground issue?
I am not too bad in mechanicals but a disaster in electricals...any easy way?
I did cut one side before taking the picturecandymancan wrote:Pink is usually 12v power.red for these Jeeps. Since it looks torn on one end and cut on thr other. Id just reconnect the wires tbh. You do see the 2 ends in the pic right ?
