Sorry, Checking the battery right off the start with a voltage meter is WRONG….. AMPS is the key , Even a dead battery reads 12.4 volts , Yes AMP testers cost money but worth every penny . Without AMPS you get no crank .

Hi. How can I check the electrics before the starter motor eg the push button and the cable that goes to the starter motor (the loose white one in this video) to make sure they are working properly?
Thanks Andy

If I had the meter in my hand and had checked the battery voltage, it would be an obvious move to look for exactly the same voltage at the starter solenoid's heavy positive cable since they're usually directly connected. If they're not at the same voltage, check connections and integrity of the cable. This is worth doing anyway, since a dodgy cable will give you a voltage reading even if it's down to it's last strand of wire. It will never carry the juice to turn the motor over though.

If all looks good, bridge the two large terminals on the solenoid with a screwdriver. If she fires up, the problem is on the control side (ie from battery positive to ignition key, to smaller positive wire on the solenoid). So you've narrowed the thing down pretty easily.

Sometimes a few judicious taps of a light hammer on the body of a starter motor will persuade it to spin. Don't overdo it.

A stop solenoid, if it has two terminals, can be checked just by putting voltage on the teminals. The plunger should pop in and out as you do.

Your alternator is broken, you should be reading from 13.8 volt to 14.7 volts

is the alternator bad if it is reading 15.8v with the tester?

Hi! watched this video ten times now. gone through my engine and changed/checked everything in the fuel system except the injectors, I do not know how to do this. I have an old Volvo penta MD6. when the compression handle is lifted the engine turns but as soon as I lower it there is no more action, no combustion of fuel at all. it took longer and longer last summer to start it up, untill one day it didnt start at all. any help from anyone is very appriciated!

Good video, need to explain in more detail what you are checking, what is a "stop solenoid". Do all
diesel engines have these? 12.8v is not good, should be above 14v. Yachting Monthly needs
to review these video's before publishing them.

If only it was so easy to access all the various component of the engine.

What is the likelihood that the contacts within the solenoid is dirty due to sparking creating resistance & voltage drop?

I expect c.14V at the alternator when running…
