i recently started a new job, and today was a slow day, so i was asked to look at a generator. i was told it kept failing the gfci test, so another employee that previously looked at it, and decided to order a new gfci. today i installed the new gfci. i turned it on, and measured 120v at the recepticals. but when i tried to test the gfci, nothing happened. to test it, i push the test button, and it's suppose to trip the circuit breaker. when i push it, nothing happens... i was told this is why they ordered the replacement gfci. i thumbed through the manual, and it gave me no insight on the problem. it said call the honda dealer. can anyone shed some light on this problem for me?
