Blower acts like a kill switch...HELP!!!!!

[BLU LUNCH]

We were on the lake today,when my son wanted to jump in and get wet. As I slowed down I put the blower on and the motor died right out like some one grounded out the juice to the distribtor. The volts dropped to 11 and then came back up when the blower was off. The motor is 3.0L. any one help on what to start checking. The blower is a brand new Attwood 4 inch blower. When we got home the blower is operating fine but I don't want to get stranded out some were. Could it be corrosion some where on the wiring,gauges or what ever...Thanks

I'm Sure it's Directly related to the Installation of your new attwood blower.....<br />I'd Start Looking There...

Sounds a lot like a bad connection, double check your battery connections for corrosion and tightness. Try some other device as well like either the trim or horn/lights also check your battery to make sure it's charged fully and no dry cells.

Just a thought, but check the battery under load. If the battery or altenater is bad you could be drawing enough amperage it rob the ignition of enough voltage to cause it not have enough oomph to fire the spark across the gap of the plugs.

I had a bad battery isolating solonoid once that any thing that drained voltage shut down the motor. Wired around the solonoid to get home and replaced for under $10.

Sounds like the added load of the blower is killing the electrical system when fully loaded. That's why it works fine alone but not when the rest of your system is running. <br /><br />Possible causes:<br /><br />1)Marginal Battery (drawing a lot of current from altenator thereby leaving little for the rest of your system)<br /><br />2) Marginal Altenator / lose belt (Not pumping rated current)<br /><br />3) Under rated altenator (not big eneough to handle your full load needs)<br /><br />4) Bad blower (sucking more than rated current - yes even brand new motors can be bad) or bad/incorrect blower installation.
