Fans won't turn on 1992 Honda Accord LX
I have a 1992 Honda Accord LX. I just replaced the radiator yesterday since the seal broke and noticed that the fans weren't coming on. I hooked the fans up to the battery directly and they work fine. I have replaced the thermostat about a month ago and all the hoses are new. I know nothing about cars other than adding fluids so any help would be appriciated. I tested the coolant temp guage sender yesterday and according to the testing procedure I found online that's not the issue. My dad put a ohmmeter on other stuff and that all looked good (so he said). I drove 20 miles home with a wire connecting the fan to the battery and was smoking like crazy when I got home although the temp guage on dash registered normal. After it cooled off I checked the radiator fluid and it was full still. My brother suggested testing the water pump so I plan on doing that today. Does anyone have any other suggestions since it's Sunday and I can't really get any kind of parts today. PLEASE HELP I need my car

1. With A/C turned on, do both fans at the radiator run? The fan on the driver’s side is the A/C condenser fan and the fan on the passenger side is the radiator fan.
2. Follow the lower radiator hose to the engine. The lower radiator hose is attached to the thermostat housing on the engine block. There is a fan switch (thermo-switch A) there. Disconnect the electrical connector (usually a green connector) from the switch. With a small paper clip or wire, jump the terminals on the electrical connector and turn the ignition to ON. Does the radiator fan run?
Even if there was a problem with the water pump, if the coolant temp. reach a certain threshold, the cooling fans should still turn on. Resolve the cooling fan issue first.

Check the things I posted previously and report back.
1. Then check the No. 29 fuse (15A) and No. 39 (20A) fuses, located in the under-hood fuse/relay box (see attached pic.). No. 29 protects the condenser fan and radiator fan control module. No. 39 protects the radiator fan motor.
2. As a quick check whether there may be a problem with the radiator fan relay (located in the same under-hood fuse/relay box), you can probably swap the power window relay with the radiator fan relay to see if anything changes. I think both relays are the same type.
Also report back regarding this items to check. It may possibly turn out to be something else such as the radiator fan control module, located inside the cabin under the driver's side dash.
