I bought 2 jet skis with trailer cheap one was a seadoo and other is a Polaris the seadoo I’m having a problem with it originally had the white motor but it went bad they replaced it with a yellow one I got the power box off a yellow motor and hooked it up I got it off eBay with all the wires but the problem I’m having I seem to not be getting power to any gauges or switch’s if I jump the solenoid across it turns over with spark but that’s the only way I can turn it over thanks
