With points or mechanical-breaker style ignition, the air gap of the points is too wide. This is usually because of wear on the contacts or maladjustment.
It's indicative of the amount of time the points are closed through the rotation of the distributor. Usually measured in degrees.
High dwell - Point gap is too small, the contacts aren't opening as far, later and for less time.
Low dwell - Point gap is too large, the contacts are opening wider, sooner and staying open longer.
When given a range value for dwell, adjust for the low value and this will allow the point gap to wear through the acceptable range before the next adjustment. Point gap should decrease as wear on the cam follower occurs, increasing dwell angle.

Explain having a too small dwell angles?
ANSWER: Having a too small dwell angle can lead to issues in the performance of a system that uses it. A dwell angle refers to the amount of time that a fuel injector or spark plug remains open during an engine's combustion cycle. If the dwell angle is too small, it can result in insufficient fuel or spark being delivered to the engine, which can lead to poor performance, such as misfires or a lack of power. Additionally, a too small dwell angle can also cause increased wear on engine components and can lead to higher emissions. It is important to have the correct dwell angle for optimal performance and longevity of the engine.
What is dwell angle in distributor?
30 degrees Dwell angle varies from vehicle to vehicle. The dwell angle is the amount of degrees the points are closed
How do you check dwell angle without a dwell angle meter?
To check the dwell angle without a dwell angle meter, you can use a multimeter set to measure resistance. Connect the multimeter leads to the ignition coil's positive terminal and the negative terminal while cranking the engine. Monitor the voltage drop as the points open and close; this can give you a rough idea of the dwell angle, as it affects the time the points are closed. Alternatively, you can use a timing light to observe the ignition timing, which indirectly reflects the dwell angle.
Point gap and dwell angle on holden 186 red?
12-16 thou gap and 34-36degree dwell angle for HR.
How do you check dwell angle?
The meter needs a dwell setting or scale. Otherwise it won't measure it with meaningful readings.
Does the timing adjustment on a 350 affect dwell angle?
no.

What is dwell setting?
Dwell is the angle at which the spark occurs in the cylinder before the piston reaches top dead center.
What is the dwell setting?
Dwell is the angle at which the spark occurs in the cylinder before the piston reaches top dead center.
What do you mean by dwell angle?
The duration in degrees when contacts are closed.
What is dwell angle of 3 cylinder engine?
22 degrees
How do you test a distributor on a 1971 Nova?
With a dwell meter you could monitor the dwell angle. If the dwell fluctuates the distributor shaft and bushings are probably worn out. The dwell should be between 28 and 32 degrees and not fluctuate.
