Question Hobbs hour meter instructions?

I have a Model 5243 15/16 and I have a Hobbs hour meter that I would like to install. The meter did not come with instructions and I am not sure what the best way to connect would be. Please respond if you are able to help me out with installation instructions for the meter on this generator. Thanks.

I must assume that you are asking about the meter. I guess that it is AC. It has two wires to it.

The hour meters I carry are made by "tiny tach"

They monitor spark pulse, they work as a tach while the engine is running (5% error) but more importantly they work as a very accurate hour meter. I think everybody should have one of these.



Back to your Hobbs, I found them here:

It appears that they have a 120v setup, and a 240 setup. You need to find out which one you have. If its a 240 volt model, you will take one wire to L1 and the other wire to L2 off the load side of the generator. If it is a 120V, you will bring one wire to the generator neutral, and one wire to L1 or L2.

MAKE SURE you put some sort of in line fuse between the hot wires and the hour meter!!

Read the 2nd half of my post.

I pulled up that hour meter via guardian's dealer access, and unfortunately it does not include any documentation.

I'm not sure if its a 120v or a 240v.
