Speaking as a trained technician. Wiring or Electrical work as pay say is not just about joining wires. Little problems can be fixed with common sense and observation liken you said. But there are some times you may need an Electrician or technician. If you love Electrical work, then pay and learn it properly. You've improved drastically learning all by your self. It might be better you learn it properly.

Also, there's a HivePower Delegation contest, where a user gets to nominate newcomers like you and I . When the nomination post is approved, the nominees get a share of HivePower Delegation. And the nominators receive the same HivePower Delegation as well.
HivePower Delegation give a user more curation rewards on post.
For example, a user with 0 HP might not be receiving reasonable rewards on his/her post. But a user with 500 HP will be getting atleast 2-3 hive votes on his post.
I'm a new comer like I said before. And I'll like to nominate you. So we can get the HP Delegation because we need it.
