Is the alternator on the right hand side of the car?
Is the alternator on the right hand side of the car?
Some alternators are described as Right Hand or Left Hand fitting. This does not refer to which side of the car it mounts, but to the orientation of the alternator mounting lugs. Please see diagram in link below.
How does an alternator connect to a stationary engine?
Remember the -ve to the battery connects directly to the frame of whatever you’re mounting the alternator onto. With your three connections made that’s it! Put the belt around the alternator pulley, connect it up to your stationary engine, make sure the alternator is turning the right way, and away you go!
Why is my Lister D alternator not charging?
The most likely cause of an alternator not charging is that it’s simply not spinning fast enough. Remember a car engine is normally running at around 2000RPM Assuming the alternator runs at the same speed as the car engine crank (they often don’t, they spin faster) then your 750RPM Lister D obviously isn’t going to turn it fast enough.
What happens when the alternator is not running?
This is the equivalent of the charge light on your car dashboard and will light using power from the battery when the alternator is not charging. This light will come on when the alternator is not running. The large connector at the opposite end of the block of three is the +ve charge to the battery.
Why is the light dimmer when the alternator is on?
As stated earlier, if the light grows dimmer as the engine is revved up, it is because the alternator voltage is rising with the RPM, producing more voltage on the alternator side of the lamp. The closer the output voltage gets to the battery voltage, the dimmer the bulb becomes.
What can you see without opening the alternator?
This diagram shows the diodes, rotor assembly and stator, all of which you wouldn’t normally see without opening the alternator. You’ll hear more about them in a little bit.
When did Delco alternators start replacing DC generators?
This is just a quick visual identification guide for Delco type alternators. First Alternator used on GM Vehicles to replace old DC Generators. External regulator mounted on the firewall. First used in 1963 on the Corvette. First internally regulated alternator used by GM. Replaced the externally regulated 10DN. Again, first used on the Corvette.
Where is the charge post on a 3 wire alternator?
A 3-wire or “OEM-style” alternator will also be internally regulated and have a charge post and two terminals on the side (viewed from the back.) Typically the left terminal is for the field or exciter circuit and the right terminal is used for the sensing circuit.
