Well Joe, don't know why you have not heard of it...
There was a service bulletin back in '99 I believe. Many control switches on the 4 stroke Suzuki re-branded units were burning up. Granted it was usually the UP side but the solution is a plug in little relay deal that went into the harness.
I don't have the part number any more...
maybe
Faztbullet or
daselbee remembers.
No, Jake, sorry. I have not heard of this relay addition either.
OP, find the TT relays under your electrical panel and locate the DOWN one.....it will have green paint on the studs that hold the wires on the relay. It will also have a large gauge GREEEN wire connected to one of the terminals. Or, it will physically be the middle one of the three round relays. Top one is UP, middle one is DOWN, and bottom one is starter.
Anyway. Get a voltmeter and attach it to the relay pick terminal and ground as you normally would to measure voltage. Then press the down button on the control. You should read +12v, and the relay should pick.
Since you say it works from the side mounted engine switch, the problem has to be in the remote control switch or in the wiring from the switch (harness) back to the engine. There MAY be bullet type connectors where the harness enters and attaches to the engine. Check those bullet connectors if present.
