Mercury 1150 Firetroubles

[nateball7777]

I found two post on this issue both seemed to be the triggers but here we go. I got the boat from my grandad he wants me to fix it up it needs alot of work i had to rewire the entire boat. I put a new switch rewired the motor and to no avail the motor turns over but does not fire. I have 12 volts on the red terminal at the switch box i turn the key one time like the ACC postion and get 12 volts on the white terminal i turn the motor over and get nothing on the green terminal this does not seem correct seeing the green terminal is what charges the coil that fires when the triggers say to. From what i have given does it seem the switch box is bad . Thank you for any help you might be able to give.

I think this is what you need, pretty sure Clams has posted this here before so I wanted to give him his due credit;<br /><br />MERCURY BATTERY-POWERED CDI TEST <br />FOR DISTRIBUTOR MODELS<br /><br />This test is for the 332-2986 switchbox used from 1967-1978 on all the inlines.<br /><br />This test assumes your coil is good (most all are).<br /><br />DISCONNCT BATTERY <br /><br />1. Turn off ignion<br />2. Disconnect all 3 wires on the distributor side of the switchbox.<br />3. Remove the HV lead from the coil to the center cap (remember it unscrews<br />from cap)<br />4. Reconnect that HV center lead to the COIL side only.<br />5. Position that HV lead about about 3/8" from ground (block, shrouds etc)<br />and find a way to hold it there.<br />6. Jumber the brown and white terminals on the dist. side of the switchbox<br />together.<br /><br />RECONNECT BATTERRY<br /><br />7. Check that you have +12 V at red terminal.<br />8. Turn on ignition and verify +12V at white terminal (on red terminal side)<br />9. Touch the black terminal to ground - unit should cause spark each time<br />you touch ground.<br /><br />If that passes and it won't fire at all, suspect the trigger.

Re: Mercury 1150 Firetroubles

I had the same problem with my 1150 this summer.I had the power to the red and white terminals but not the green.The mec. said it was the trigger and he replaced it and it fires perfect every time now.

You don't have to thank me. I already got my own thread welcoming me to this board. <br /><br />But seriously... Everything I know about the inlines came from doing two things: Reading the Mercury manuals as bedtime reading for a whole summer, and picking the brains of the older experts. Racers like Sam C., Jeff G., and Norris, come to mind for openers as well as a feller local to me, Larry R., who frequesnts John's board and restores older inlines for a hobby. (he collectcs them like butterflies).<br /><br />All I'm doing is passing it on....<br /><br />-W
