What does system relay do on Harley?
It isolates most of the systems on the bike from the main electrical bus when the ignition is turned off.

Did you have any codes before you cleared them?

Dead battery, main circuit breaker is automatic resetting so it probably isn't that. Check battery connections for corrosion.

oil pressure switch is working and when at working pressure light goes out

To check for trouble codes turn the ignition switch to run for three seconds (one second pause after the fuel pump stops running) and then turn the switch back to off for three seconds. Repeat this process again. Now turn the switch to ignition and wait for about 8 seconds and the check engine lamp will start flashing the codes. If there are codes present the light will flash rapidly (about three per second) then there will be a 2 second pause with the lamp off. The lamp will then flash one or more times to indicate the first digit of the trouble code. It will be on and off for about 1 second. Count the number of times it flashes for the first digit of the trouble code. Then there will be about a 2 second delay then will flash again for the second digit. After flashing the second digit there will be a 2 second delay and additional trouble codes will be flashed. Write down the numbers and when they start repeating themselves the trouble code transmission is completed. All trouble codes consist of two digits.
If the lamp flashes only the 3 flashes per second there are no trouble codes present.
If there are codes present, let me know and I can advise you of their meaning.

Set the alarm by holding the key fob button until you see running lights flash twice. Turn off the alarm by pushing the key fob button twice and the lights will flash once.
