The Nitro Euro Style Rollator has unrivalled folding capabilities: It easily collapses to an ultra-compact size with one hand by pulling the seat grip up and bringing the ergonomic, height-adjustable handles together so they almost touch.
What happens if your alternator does not start charging?
If the alternator “sings” and your voltmeter jumps up to show charging voltage, the alternator is likely good and you must move your focus to the wiring leading to the regulator connection. If it doesn’t start charging, the alternator is definitely bad and it’s time to sell a new or reman unit to the customer.
How is DC current handled in an alternator?
The process of rectifying the AC current into DC current is handled inside the alternator by something more complex than a commutator – diodes. A diode is a “solid state” device that allows current to flow in one direction only – “solid state” means it does this without any mechanical or moving parts.
What does it mean if your alternator is shorted in both directions?
You should have continuity in one direction and if you switch leads you’ll have no continuity. This will tell you the diodes are good or shorted in the alternator. If you have continuity in both directions then the large post is grounded or the internal diodes are bad.
What should I do if my alternator wont work?
If you have continuity in both directions then the large post is grounded or the internal diodes are bad. If you can’t get it to work and you decide to get this fixed, consider contacting a certified mechanic who can diagnose your electrical issues firsthand and fix it accordingly.
Why does the alternator keep blowing when power is applied?

Can a bad alternator keep a car going indefinitely?
An alternator can help replenish the battery in your car, but it can’t keep it going indefinitely. This means it’s important to distinguish between a weak battery and a bad alternator.
What happens when the diodes in an alternator go bad?
Alternators use diodes to rectify alternating current produced by the alternator into direct current. When one or more diodes go bad, the alternator can cause all kinds of problems. AC voltage leak can cause your lights to dim and drain power from your battery, for example.
How to diagnose an alternator or electrical problem?
Diagnosing alternator problems can be a bit tricky because the electrical system in a car comes from two places, the battery and the alternator. I’ll give you a little background so you can understand what both systems do. The battery has one primary function, which is to start the car.
What causes an alternator to stop working on a car?
Once the alternator stops working, so do all of the electrical systems required to keep a car going. Other problems can also cause a car to not start. It could be a bad starter, corroded cables, or a broken connection somewhere between the battery and starter.
