How to set points on a 1975 Nissan Datsun 1600 pup


It would be much easier to show you than to describe the process - there might be a helpful youtube video...
My description is best practice that can be curtailed somewhat if necessary.

Replacing the the contact breaker points requires several distinct operations to ensure the reliability of the car for a reasonable time.
I am not familiar with your model but the process is similar on all but a few models.

Remove the old contact set and wipe the distributor cam clean. Inspect the baseplate ground lead if fitted, Inspect the rotor arm and distributor cap. Place one drop of light machine oil on the baseplate pivot and two drops in the shaft centre. Oil the cam lubricating wick if fitted or smear HMP grease sparingly on the cam lobes.
Check the vacuum unit if fitted and ensure the baseplate moves smoothly.

Fit the new contact set and roughly adjust the gap. Connect the dwell meter and crank the engine (best done with spark plugs removed) until the dwell angle reading is obtained. Increase the gap a little if the reading is higher than specified and reduce the gap if the reading is too low.
Once the obtained dwell angle is correct, check the physical points gap with spotlessly clean feeler gauges. If the gap is within specifications the distributor cam is not worn. Check the gap on all the lobes to ensure they are equal.

Fit the rotor arm ensuring any wiring is pushed down and is not going to foul anything. Fit the distributor cap. Check the spark plug condition and gaps and refit them. Start the engine and check/adjust the timing using a timing light (stroboscope).

Once the engine is at working temperature the idle speed and air/fuel mixture should be checked and adjusted.

Cars fitted with contact breakers should receive these checks and adjustments about every 6000 miles...

1971 Honda CB 100 will not turn over


Hi, Anonymous before testing any electrical component in the Starting System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead acid batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand, clutch, neutral safety switch.
9. Security alarm needs a reset.
10. Starter relay, solenoid, starter motor or circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. Faulty ignition relay.
14. The electric starter is working but starter clutch has failed.
15. Check for engine trouble codes.

Why does circuit breaker spark when turned on?


When any switch or circuit breaker is turned on, and there is a load present, there will be an arc as the current jumps the small gap between the contacts just before they actually touch. For example, if you could see inside a simple light switch you would see this arc as you either turn the switch on or turn it off. On the other hand, if there was no light bulb in the fixture, (this is the no-load situation) there would be no spark. The higher the voltage, the greater the gap that can be jumped. The larger the load (say more, high-watt light bulbs) the larger the spark. Most switches are designed to snap quickly through the position when the contacts are close together, so that the spark doesn't cause too much damage to the contacts.
