My tilt stopped working on my throttle handle but still works on the motor itself. Are the buttons on the handle simple enough to replace in my driveway? It is a Suzuki throttle controller working a Yammy Vmax150. Any info will help thanks!

There are 3 wires going to your trim switch on the throttle, probably connected with bullet connectors. There will be a red wire, a blue wire and a green wire. Unplug these 3 in the console. Test to make sure there is 12V on the red wire at the harness. I suspect that is the problem if it won’t go up or down. If there is 12V on the red, jumper the red to the blue and engine should trim up. Jumper the red to the green and engine should trim down. It is unlikely that both up and down switches have failed simultaneously, so you have probably lost the 12V feed. Probably bad connection or fuse.

Thanks for the heads up! I will check this afternoon and get back to you.

Thanks Larry, checked it out and found the three wires. Had 12vdc on red. Jumped wires and engine tilted both ways no problem. Must be internal on the switch even though it’s epoxy sealed. I imagine over time it gets in where the switch rocks. Anyway thanks a million for the wise words! Looking into finding a replacement switch now. Thanks again man

Welcome. Been there, done that same troubleshooting a few times before. Got to have 12V on red, blue is up like the sky, green is down like the grass. It’s pretty much an industry standard color code for trim harness.
Might be internal to the switches, or the wire pinched somewhere higher up in the control box might also a possibility. I don’t know anything about Suzuki control boxes and how the wires connect to the switches. Sorry.
If you can work a volt meter, can you work an ohm meter? With the 3 wire harness disconnected, on the switch side of the harness connect an ohm meter between the red and green and have someone else push the trim down switch. The ohm meter should go from open to short circuit. Do the same thing from red to blue, pushing the up switch. It should go from open to short.
I recently had to troubleshoot a new Yamaha that the trim up wasn’t working. It turned out to be a bad bullet connection on the Yamaha harness where it plugs into the control box harness. A month later the trim down quit working. Another bad bullet connector on the Yamaha harness. So test the switch on both sides with an ohm meter. If the switch works, highly suspect those factory bullet connectors may be bad and not making a good connection. Wiggle them around while somebody else pushes the switch. With Ign. switch on, of course. You got it narrowed down now. I cut out the bullet connectors and spliced them. Problem solved. I’d still bet on a bad connection and not the switches, but my advice is worth what you paid for it. I’ve been wrong before

make sure you can get the replacement part before you take it apart

IF I RESPOND IN ALL CAPS, ITS NOT ON PURPOSE, AND I AM NOT YELLING
Well, cleaned up the ends and tried with the continuity meter, even cut the bullet connectors off to bare copper and everything leads to bad switch!
blue is up like the sky, green is down like the grass How simple and effective!
make sure you can get the replacement part before you take it apart 3 hours of searching and finally found this!
Thanks again fellas!!

Ok well I recieved my handle/trim switch package and decided to bench test it before I installed. From green to red (down) gave continuity but blue to red did not. I polity ask what the return process was for my purchase as it did not work and I didnt wasnt to eat the 65$. The guys replied to me that Suzuki had a diff color code than other marine product and instructed me to check it again before he would reluctantly give me a refund even though he had it clearly marked as no returns. Turns out the guy was right as rain and the green is the hot and pink/red is down and blue is up. Suzuki owners pay attention to this as you might be fooled as well. I plan to install today now that I know it works. I went ahead and did some research on my own too, here is what I found…

Right about the middle of the chart it shows the typical color codes for most marine wires.
Ended up giving the guy a stellar review and thanked him for walking me thru the issue! Hope this helps someone else not get fustrated thinking they bought something faulty when it realy wasn’t.
