Hi
My motorcycle uses an old style 12VDC fuel pump with a solenoid and a set contact breaker points.
The points are subject to arcing which can shorten their life and there is no suppression built in such as the condenser (capacitor) that was used on distributors before contactless ignition systems became common.
I've read that the arcing can be suppressed or reduced by putting a diode in parallel with the solenoid. See here for example:
**broken link removed**
The explanation sounds ok but I would like to hear from automotive electronic experts if they think this would do any good. Why I have doubt is that if the solution was so simple, why wouldn't the manufacturer put a 10 cent diode in in the first place?
Thanks in advance.
