DC motor question

The item in question is the reversing relay. This is a simple and inexpensive component to replace. You should be able to find something suitable in an automotive supply shop. It helps to take the broken one with you so you can get a replacement with the correct coil voltage and contact current rating.

Hi, Just repaired the same problem on an older OMC V-4 outboard. Installed a couple of good 12v relays and got it to working intermittently. The grounds looked good, but closer inspection revealed otherwise. An hour of cleaning and replacing terminal ends returned normal and satisfactory operation. Good Luck, Regards, Jay

Thanks for your replies. Turns out it was a bimetalic cutout in case of over heating of the motor. I've bypassed it and all is well, I just have to remember not to adjust my tilt and trim for a solid hour and burn up my motor.

I always like to see people that bypass safety devices and say all is well. Did it ever occur to you to replace the cutout?

Sorry, forgot to login. I am the guest on comment #4

I should have elaborated. I bypassed it and everything worked. I thought about it and ordered up new springs and brushes. I am currently looking for a cutout to replace the old corroded one. Of course finding Yamaha specs on something that deep is presenting quite a challenge, they would prefer I buy a new motor. Thanks

PS the correct terminology is a bimetallic thermal cutout switch. There are many available but I need the proper temp, and it has to fit in the space. Any thoughts would be appreciated.
