Observe both testers ammetervoltage meter as you crank the engine.
. Just took solenoid apart it looked pretty good so no obvious cause there. Due to the inductive reactance of the motor spinning faster with 12 volts the. The choke solenoid could just have a suitable resistor placed in series with it with resistance same as the solenoid to soak up half the voltage but watch the power rating of the resistor you want to have a power rating thats above pv-squared over r or p 36r.
If I consider that the round trip both pos and neg cables will be a little over 76 meters you are suggesting that the starter will be drawing over 100 amps. Under winter conditions this current can easily double when the oil is thick. This in turn starts the outboard engine.
From a practical standpoint should the starter fail it. The A4 starter Delco draws 125 amps. I have a 16 starcraft with a 40hp 3cyl Yamaha and tried to move the Optima bluetop 27 series starting battery to the bow with 15 feet of 4 gauge wire.
Currently there are 0 users and 1 guest visiting this topic. Never crank the engine for more than 15 seconds and allow the starter to cool for 2 minutes between cranks. Viewing 8 posts - 1 through 8 of 8 total wet-willie Replies.
Water in the system. This part is responsible for transmitting battery voltage to your starting motor. Engine Does not Start.
Set the voltage meter to measure battery voltage 126V. Bad software issuesFuel issuesEngine water pressure issuesBad spark plugs. Large displacement outboard motors do this as a rule.
Initially for a brief moment in time it will be higher than the steady state flow. That seems extremely excessive amount of energy to fire such a small motor. A Quick Overview to Evinrude E-TEC 115 Outboard Issues and The Reasons Behind Them.
That is the steady reading after the current flow had settled down. Maybe as much as 350because of this high current flow it probably isnt practical to try to fuse the circuit. Oct 6 2010.
Shown below is a typical Yamaha starter circuit. This topic has 7 replies 5 voices and was last updated 5 years 11 months ago by frankr. The contact located inside the starter solenoid activates a circuit to open and allow electrical current to transmit from the battery to the boats starter.
Outboard Motor Starter Current Draw. If the engine does not start do not keep trying to start it as it will not for those who pull that stunt. Id like to know how many amps the.
Home Forum Ask A Member Starter current draw on 56 Big Twin 30. If its a small hp 20 or under possibly larger it probably has a pull start as well and you can start it. Of one relay and the NC.
From the key switch current flows through first the starter relay to ground. Agreed but thought it would be diagnostic ie. I want to put a backup 12v battery in my truck and I was thinking of using 2 battery cut-off switches to switch each battery in and out of the system.
If your cable from the battery to the starter is an AWG 2 it is rated for 178A in an engine space so you should use a 175A fuse. Old engine modelBad exhaust issues. The clicking is the sound of the solenoid trying to get the starter motor to engage.
I have a wind generator and 2x80w solar which. Current then flows across the relay power contacts and then on to and through the starter solenoid to ground but only through the solenoid coils. A 50A fuse is far too small.
221 and require more powerfull starter motors. Couldnt come close to getting the motor to start. I currently have 5 x110AH batteries configured as a 3 and 2.
5 October 29 2015 at 1203 am 2872. Based upon automotive starters I would say your starter will draw over 200 amps. You figure about drawing about 20-22 amps for short bursts.
Typical amperage draw is a ton of amps. If starter does not draw its rated current that would explain why it does not start with enough torque to move Bendix into engagement with flywheel ring gear. A faulty solenoid could prevent the starter from getting power.
I think I would have to use 20 or larger cable to minimize. A starter motor from a normal 2 Litre petrol car draws between 60 and 200 Amps when turning over the engine when the oil is warm and thin. Disable the fuel or ignition so the engine will not start during the test.
You probably have a fouled carburetor just like a foul duck trying to poop in the boatu000bu000bYou can use either 8 or 6 but if you want to be really safe then use 6. They are all leisure batteries which at times do get over -discharged even so they have all done 5 years of use abuse. Diesel engines have a very high compression ratio eg.
Thanked 78 Times in 55 Posts. So looks like the disassembling the starter motor again is the only move left. Any ideas what the cranking current would be for a 20hp outboard.
None of this current flows through the starter motor itself. 2 04-17-2014 0933 PM I cant say what it should draw but I can say that I put a clamp-on ammeter on several large HP Yams and the current draw was more or less 165 amps. To size the fuse remember you are protecting the cable not the load starter.
