Re: Battery cables were hooked up backwards now tilt/trim won't work
Hooking the cables backwards wouldn't have any effect on the PTT assy, nor would it cause a fuse to fail. I'd suspect that you neglected to hook up a seperate cable pertainihng to the PTT unit, or the cables are not properly tightened.... or they're tight but dirty.<br /><br />However, hooking the cables up backwards, or connecting a battery charger up backwards will result in destroying the charging rectifier, which you should replace immediately. It does not matter whether the key is off, on, or in the start position due to the fact that voltage is applied to the red lead of the rectifier constantly when the cables are connected to the battery.<br /><br />The rectifier will be on the starboard (right) side of the engine, directly in front of the wiring terminal strip. It will be about 1" in diameter, 1" high, have a triangular like shaped base, and will have 3 wires leading from it.... Yellow, Yellow/Gray, and red (some have 2 yellows).<br /><br />You can test the rectifier as follows:<br /><br />(Small Rectifier Test)<br />(J. Reeves)<br /><br />Remove the rectifier wires from the terminal block. Using a ohm meter, connect the black lead of the ohm meter to the rectifier base (ground), then one by one, connect the red lead of the ohm meter to the yellow, yellow/gray, then the red wire (some rectifiers may also have a yellow/blue wire. If so connect to that also). Now, reverse the ohm meter leads and check those same wires again. You should get a reading in one direction, and none at all in the other direction. <br /><br />Now, connect the black lead of the ohm meter to the red wire. One by one, connect the red lead of the ohm meter to the yellow, yellow/gray, and if present, the yellow/blue wire. Then reverse the leads, checking the wires again. Once more, you should get a reading in one direction and none in the other. <br /><br />Note that the reading obtained from the red rectifier wire will be lower then what is obtained from the other wires. <br /><br />Any deviation from the "Reading", "No Reading" as above indicates a faulty rectifier. Note that a rectifier will not tolerate reverse polarity. Simply touching the battery with the cables in the reverse order or hooking up a battery charger backwards will blow the diodes in the rectifier assy immediately. Good luck.
