1988 Starter Issue

[Therman]

I have a 1988 70 hp that the starter does not have enough power to fully turn he flywheel. I jumped straight from battery to starter with the same result. What does this mean and does it rule out the soleniod.

Re: 1988 Starter Issue

I think it rules out the solenoid, but did you jump both leads directly to the
starter, or just the hot lead? You could have a high resistance connection
in the ground lead to the block. Check that by jumping directly from the
battery neg terminal to the block, then jumping hot directly to the starter.

If you turn the flywheel by hand, do you get the normal easy/hard, easy/hard
feel from compression, or is the flywheel real hard to turn?

Re: 1988 Starter Issue

Is your battery fully charged ?? Have you had it load tested lately ??

Re: 1988 Starter Issue

I jumped only the hot lead to the starter. What am i looking for when I jump the negative battery terminal the the block. When I turn the flywheel I get the normal comperssion feeling. The battery shows 12.8 volts and im getting it load tested tommrow. Also, is there an engine ground somewhere else that goes from the block to somewhere?

Re: 1988 Starter Issue

Does the battery test 12.8 when you turn the key? Hold volt meter on while someone turns key. See what the meter reads. I would think it should not drop below 12.4. Motor would not turn over last weekend. went after ground wires. turned out to be the positive terminal that goes to the battery. Replaced the terminal engine fired up.

Ok ill check the voltages. The starter has three mounting screws, im only useing two could that be messing up the ground from the starter to the block.

Re: 1988 Starter Issue

I had my battery load tested it was bad so bought a new one, but same problem. I jumped from negative battery terminal to block and from postive battery termainal straight to starter and still the starter hardly spun the flywheel nowhere close to makeing the engine fire. I have no idea what to do next any help would be appriciated.

Re: 1988 Starter Issue

K- can you ground straight to one of the two bolts you have holding the starter on? what is the color of the two small wires on the starter solenoid? one black one yellow (maybe)? The big black wire coming off the battery if you follow it , it should be attached to the motor block some where make sure it is tight and the wires going into the terminal is tight.

ya, i have cleaned all connections and retightend them.

Re: 1988 Starter Issue

K-Therman hope you are doing the small test. this is a harsh and old school test to check the solenoid. you can jump the solenoid. Take a pair of channel lock pliers with insulation on the handles and place one side of the pliers to one of the big post on the solenoid and the other side of the pliers to the other big post on the solenoid this will give you straight juice to the battery. There will be some sparking so be ready. if the motor turns over then it is the solenoid. if it does not then take the starter off and have it tested (free) at any auto Zone or any auto parts house.If the starter checks good then it is more then likely a bad connection somewhere.

Re: 1988 Starter Issue

sorry I should have said straight to the starter and not battery.

Re: 1988 Starter Issue

ok. I jumped the soleniod and got the same results, the flywheel barley turning. The starter is brand new could it have gone bad that quick.

Re: 1988 Starter Issue

did you trace the neg wire from the battery to where it hooks on to the engine block? if so was that connection tight? new battery, did you put a meter on it to see if it was fully charged? sometimes they sit on the shelf a while. I would not think the starter would be bad but you never know. Has the starter that you have ever cranked the boat before? has fast does the stater spin as the gear is moving up to engage the fly wheel? it should move really quick. As long as you have a good ground from the battery to the engine block I would say two bolts would be enough to make a good ground. do you have a jump box? one of those things you can jump a car or something off with. If so we can by pass the battery and hook it to the solenoid
