I have a 96 yamaha vx250 2 stroke carbed motor. i had to replace the battery today and when doing so mistakenly hooked up the battery cables wrong. The engine and all gauges work fine but after 20 minutes my oil alarm went off. Oil is not pumping from the remote tank to the one on the motor. Is is possible that i fried the pump motor or possibly the computer?

Are you sure it's not because the main tank is low? At about a third full it quits pumping and you have to use the manual switch.

I was able to test it this morning (much more quiet without my crew aboard) The pump makes noise when hitting the switch but oil is not going to the tank. Should hopefully just be a clogged filter.

plugged inline oil filter or a pinched oil line

If the remote tank is full , is the gauge indicating it properly
