If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, read through the following page:

Let me know if you have any other questions.

How do i trouble shoot a delphi 4.0 bike meter. every feature is working except the cadence? is there a battery in the little unit that goes down by the rear wheel


First, make sure that the sender is connected. There should be a device on the frame over which the magnet attached to the pedal passes. Unless you have the sender that is attached to the pedals you will obviously not get a cadence. secondly, on my Vetta device one has to select cadence. Check the manual to find out how to do that. I'm sure there is one online.

Sigma BC 1609 Cadence Bicycle Speedometer reads my movement much slower than I am actually going. E.g. moving about 15, reads as 5 mph.


I had the same problem. It is caused because the mount is facing the wrong direction and your computer is swapping speed and cadence. 5 mph would mean 63 RPM of the wheel which probably what your pedal is actually doing. The wheel is actually turning at about 3 times that rate so if you check your cadence it is probably maxing out at 180 even though that wouldn't be possible.

To fix this, just twist your mount 180 degrees on your handlebars or stem and try again. That way the computer is correctly lined up with the mount.

Diagnosis light


It could be an overheating or power issue. It may be that the two speakers are loading it too much, which will cause it to overheat. Does the light eventually go off and the sound return ? Do you have the speakers wired in series or parallel ? What's the impedance of the speakers and the minimum continuous load for the amp ?
