Re: Can anyone help me get a part

my battery reads 12.75 volts its a brand new sears die hard 675 cca. i usually just say 12volts . eurolarva you mean my ignition switch might be lower resistance ? so its possible that the coil inside of the solenoid is only pulling 8 or 8 and a half volts? so with eurolarva readings and mine i am about 2 volts under his. and my solenoid is reading at 0.4 if i did it right i have 30 amps? its pulling? if any of you guys want to give me a call its quicker than typeing you can call collect or reverse the charges or if you have verizon its free cell phone to cell phone my cell is 609 405 5797 home # is 609 893 3238. i am in new jersey east coast thanks for the help guys i do appreciate it.

Re: Can anyone help me get a part

Even though the voltage at the solinoid is only 8.8 volts I bet when you read the voltage across the battery with the choke engaged the battery will still read 12.75 volts.<br /><br />I took a spare solinoid and hooked it up to my 10 amp battery charger. I connected the volt meter to the solinoid. When I plugged in the battery charger the solinoid engaged and only read 8.8 volts on the volt meter however it was enough to cause the solinoid to engage. As I stated earlier I believe that with the wire going to the switch and back to the terminal block and to the solinoid that the battery can not put out enough current to make the solinoid read 12 volts. The wire to the switch is about 22 guage wire and with all the connections the wire and the connections are probably dropping about .4 ohms. If this is the case the .4 ohms of wire and connections and the .6 ohms of coil resistance equals about 1 ohm. This also creates a voltage divider where 40 percent of the voltage is being dropped across the wire and 60 percent is going to the coil. Sorry if this is getting too technical but I dont think it is possible for you to ever see 12 volts at that solinoid. Make sure all your connections on the switch and terminal block are shiney and tight. That will reduce the loss of electricity. I am willing to bet because you have a new battery that your choke problem will go away.<br /><br />Starter uses like 4 guage wire is is triggered by a small wire to turn on the solinoid. So actual power to the starter is raw power off the battery via heavy cables.<br /><br />Make sure that the metal areas on the choke solinoid are clean and shiny where they come in contact with the motor and the mounting screws. I would call but I dont think I can make this clearer. I am logged on to yahoo messenger and am called printergod2000 there. I will be logged on for about another half hour.<br /><br />Good Luck

Re: Can anyone help me get a part

ok eurolarva , larry i got a third choke solenoid put that in got a reading of 8 and a half volts the solenoid does engaged , eurolarva thanks for checking yours i feel a lot better knowing that yours read the same as mine you reply makes perfect sense , i cleaned all the wires good connections new battery so i think i will be ok larry good talking to you last night, i didnt get an dc amp gauge yet, might not need one now. but last week the starter was cranking strong, just the choke solenoid wasnt engaging which i knew if the started was spinning it had to be enough for the solenoid so hopefully that solenoid was just acting up being a little funny so in the garbage that goes. taking out the boat tomorrow and thanks again guys .

Higher end fluke meters will read about 2 amps. This is not enough to read the current the solinoid is pulling. An attachement is availible for a digital meter which clamps on a wire and will read current however these cost between 150 dollars and 250 dollars. If you know the resistance across the solinoid which say is .6 ohms and your reading 8.5VDC across the solinoid you are pulling about 14.2 amps.

eurolarva what size amp fuse for my ignition switch? its a 89 force 85 hp. anyone? thanks

I am a chrysler guy. I dont think the ignition has a fuse. Maybe item 38 HERE

Re: Can anyone help me get a part

when measuring the voltage between the coil positive feed and ground your actually measuring the voltage across the soilinoid coils. they will act as a dropping resistor. if you dont belive it hold it in ten minutes and see how hot the case gets. if you remove the coil power supply wire from one side of the terminal and test between the harness side and ground you will read battery voltage if all other connections are good. but when you add the solinoid coil you just added a load. you rarely see battery voltage across the load.<br /> if your meter has an auto ranging function use it. auto is your german buddy. he will keep you out of trouble. alway remember voltage is just a potential or electrical pressure. its possible to read battery voltage across a bad connection but it will go away if loaded. but your numbers are coming up about right for your solinoid. they take a lot of current. but do keep checking the circuit for dirty contacts. start at the ign feed on the ign swith to ground with the choke on. then move to the choke terminal to ground, then to the terminal stip on the motor to ground. all should stay within a volt or so. if they dont you will need to do a voltage drop test on the keyswith then the harness.occasoinally you will find that if connections are dirty or poor anywhere the starter will crank but draw all the availible current and the smaller accessories get none. if your unsure do a voltage drop test across the battery cables and starter solinoid.

Re: Can anyone help me get a part

good to here that the solenoid reads good under a load . so i have o good solenoid she works . cleaned all contacts so i hope the first time it was just a bad solenoid or i should say going bad. took the boat out saturday ,she choke fine she didnt want to start so i took the cover off the top and pust down on the linkage to choke her and she started. but my fault when i installed the solenoid i didnt have her down far enough for the shutters to completly close so i readjusted the solenoid down a bit farther with me holding the linkage down so she is closed all the way now it should work fine. just one thing when i had the wife in the boat chokeing the solenoid i pushed the linkage down it went about an 1/8 inch more (thats how i knew it wasnt choking all the way) anyway the fuse blew it was a 15 amp when i turn the key nothing usually the gas meter and dash lights up so i replaced the fuse just wanted to make sure its not suppose to be a 20 amp could i of blown the fuse while the wife held in the choke while i push down the plunger to adjust the choke? i overloaded it? i think the post above said it will draw about 14.2 amps . thanks again

Re: Can anyone help me get a part

If the fuse is a slo blow it will take above 15 amps for probably at least 5 seconds before it blows. If your old solinoid resistance dropped to under .5 ohms that would probably put you above 15 amps on the circuit Choke should only need to be engaged for a few seconds on a good running motor. Usually just enough for it to start and then occasionally goosing the choke till it warms up.

Re: Can anyone help me get a part

but does anyone know what fuse i should have in there / 15 amp or 20 amp. theres been a 15 in there when i bought the boat just double checking to make sure its the right one. it doesnt say in my service manal. also finish adjusting choke solenoid to factory specs i shouldnt have any more problems now. thanks
