Re: ignition switch wiring
This will give you some idea about what wire is used for what.<br />Those guys are right a good manuel is money well spent.<br /><br />Here are the standard wire colors used in the boating industry since the late 70s. When re-powering a boat with a newer motor this is a handy reference. Most boats use these standards but always double check in case changes have been made! <br />-------------------------------------------------------------------------------- <br />BIA Wire Color--------------------Where it is used <br />-------------------------------------------------------------------------------- <br />Black---------------------------------All Grounds <br />-------------------------------------------------------------------------------- <br />Black with Yellow stripe---------Magneto/short to Kill <br />-------------------------------------------------------------------------------- <br />Gray----------------------------------Tachometer signal <br />-------------------------------------------------------------------------------- <br />Yellow with Black stripe---------Choke <br />-------------------------------------------------------------------------------- <br />Red----------------------------------Unprotected(12V+)from battery <br />-------------------------------------------------------------------------------- <br />Red with Purple stripe-----------Protected(+12V)from battery <br />-------------------------------------------------------------------------------- <br />Purple-----------------------------(+12V)from ignition switch <br />-------------------------------------------------------------------------------- <br />Tan------------------------------Overheat sensor to warning horn <br />-------------------------------------------------------------------------------- <br />Pink-------------------------------Sending unit to fuel guage <br />-------------------------------------------------------------------------------- <br />Yellow with Red stripe----Ignition switch to starter solenoid <br />-------------------------------------------------------------------------------- <br />Yellow-----------------------------charging stator to rectifier <br />-------------------------------------------------------------------------------- <br />Lt.Blue with White stripe--------Trim up <br />-------------------------------------------------------------------------------- <br />Green with White stripe-----------Trim down <br /><br /><br />-------------------------------------------------------------------------------- <br />Some more standard wire colors used on many inboard boats, always double check though, as some vary or may have been changed along the way! <br />Some standard colors for boats since 1980 are as follows: <br />· heavy red 10 guage (main battery) <br />· heavy black (main ground) <br />· purple (ignition) <br />· yellow (starter solonoid) <br />· grey (tachometer) <br />· brown (temperature) <br />· blue (oil pressure) <br />· brown with stripe (alarm) <br />Accesories <br />· pink (fuel sending unit) <br />· yellow (blower) <br />· brown (bilge pump) <br />· grey (navigation lights) <br />· heavy green (bonding wire) <br />· red (misc electrical add-ons , vhf , depth finder, stereo, radar, power supplies)
