Hello. My name is Tan.
Could I get the make, model and serial number of the engine you are working on please?
Do you have a volt meter to do some voltage tests? Have you tried resetting the circuit breaker on the engine?
Ok we need to do some voltage tests to find where the problem is. Do you have a volt meter to do some voltage tests?
Can you get one? Is it possible you reversed the battery cables when you replaced the battery?
Without a voltmeter I can only guess what the problem is. I can give you the most likely cause.
