Starting Problems

[champ370]

I have a 1990 90hp Force outboard. I've only had the boat in the water three times. On the third time she didnt want to start.
I have 12.64vdc in to the silonid and when i turn the key I am only getting 9-10vdc on the secoundary side. The starter is spinning, and the engine is free.
I don't know if its a bad batt, a bad starter, or soiloid. Can anyone help me with this???

Re: Starting Problems

Hey, I own a FORCE 90 hp almost new (5 hrs run) when i bought 10 years bf.The last three years the engine turn with full charge battery 14 volts on the gauge but was turning weak and didn't start until i drop gasoline in the cylinder from the spark with an orange straw.After quickly back the spark in position ,turn on key and engine starts.If for long time in the parking .In the sea she was working normal by the key,of course before leave the parking always happen the above show!!
And this summer I found out that the main electrical cable fm engine to batt. from a small hole on the insulant which god knows how happen all the years pick up salt ,moissture,water,dust,e.t.c and when i took on hands i saw full of suprise that inside it was totally cutt (nothing was to see fm outside exept if your hand catch it fm the trouble point and it bends on hand then you can see)and only the outside was keeping that and the last years was working only by the ark to pass current fm batt. to engine.Now i change that cable engine turns powerfully when i start normal by the key .
check your cables very carefully cm by cm !

2.Your battery needs charge (this i believe is your trouble) must shows 13,5 volts alone and 10,5 or more when using starter !

I hope i help a little.........

Re: Starting Problems

First, make sure your battery is relatively new and fully charged. It should read about 12.6 or above if fully charged.

Next, clean the contacts on the cables at the battery, the solinoid and the engine block grounds.

After that, try to start it. If you get more than a 1.5 volt drop at the starter positive lead, you have a problem. It can be the starter, the solinoid or your cables.

Next, put your meter on the positive side of the solinoid and try to start. If the voltage drop is less than it was at the starter, the solinoid has pitted contacts.

If the voltage drop is still more than 1.5, place your meter at the battery terminal and try starting. If the voltage drop is less than 1.5, your cable is bad. If it is still the same, take your battey and have it checked at Sams Club or Walmart and pick up a new one because it is bad.
