| Subject: | Can a low voltage situation cause a fuse to blow? |
Hello all. First, let me say that have very little education in the electronics
field, but I do know the basics. I recently got hired as a service tech for pressure
washers and had encountered a unit that had a small engine (electric start
12v) with a blown fuse. A co-worker of mine has been doing this work for
about 15 years. He is the know it all type. Very good with wiring and troubleshooting
electrical problems with the bigger electrical units (120v - 460v), however
he told me that the reason this machine I was working on blew a fuse because
the battery was low(which it was dead when it came in). I explained to him
that according to my understanding of ohms law, that doesn't make sense. If
the voltage was low the amperage should have dropped too. Is this correct? He
told me that he has seen when low voltage had caused a fuse to blow or breaker
to trip (in high voltage machines). Is there any situation at all that this would
be true? It is really making me curious. Thanks for any insight you can help
provide.
