Volvo Penta EDC KAMD 44P On Engine Wiring Introduction

This video covers the components and wiring under the small electrical cover on older Volvo Penta TAMD 44 EDC series engines. This follows the previous video about the wiring that leads from the engine up to the helm station and back. I cover what components are on the engine and some of their functions - it's a brief overview but it shows where they are and what they look like. I am working on a 3rd video which will tie these past 2 together better and show how to trace the circuits with wiring schematics.

Love your videos. I have two 98 KAMD44PA’s. Learn a lot from your tutorials. Appreciate your time.

Thanks for the positive comments!

Thanks for this one, Ted. I had an intermittent no crank condition on one of my 44s last season. Drove me mad until I got the wiring diagram and traced things out. Turns out it was corrosion across the normally closed contacts of the stop relay. I did a wholesale change of all relays in both motors and it's been good ever since. Thanks for the video!

Love the KAD44 videos Ted. Learned a plethora of information from you. One thing I hate is how my gauge voltage is lower than actual charging voltage due to these diodes. I was having charging issues awhile ago and couldn't understand why alternator voltage was so much different than my gauge voltage. Then traced it down to the diodes. Almost a full volt voltage drop across it. Everything I've read, this was normal. Anyways, Thanks for the videos. Keep the kad44 videos coming!

Ted,thank you for all your videos, please explain the need for the resistor as I'm rewiring a 41

[@mikedesmedt9779]

hello ted. i have a KAD 44 since last week the 2 fuses blow every 15 min. any idea what the problem could be?

[@syedpeeran3133]

Thanx to sir ur guides I follow up sir..

Hey Ted,
Thanks a lot for your explanation.
Do you have any fuel consumption diagrams of this engine 🤔...
I thinking to use only one engine for slow driving 5to6kt at 1k to 1.250rpm.
I have a shaft driving propeller. So i think i have bo problems with the gearbox of the not running engine.
The exhaust have a rubber closing thing outside, so no water came into the engine over the Turbo and exhaust valve.
So i think i can go by only one engine without damage anything in the not running engine.
What do you think?
And what do you think about the fuel consumption that i can safe?
I guess it was about 30 to 40% .
The gearbox is always filled with oil, so it doesn't matter if some gears rotate when the propeller turns from the running water.
Thank you very much

Am inspecting a 2000 model boat. It has Rust in coolant KAD44 on the “fresh water side”
Do you have a recommendation for treatment. Also I am wondering if this might be the symptom and not the problem

[@tedsmarinerepair8956]

It is hard to tell why rust would be in the coolant, but not changing it on a regular basis would be a likely culprit. The recommendation is to remove the drains, drain the coolant system and flush it with good tap water (no well water) let the water flow into the expansion tank until it runs clear out of all the drains. Stop filling and install drains, Refill with distilled water and run the engine until it reaches operating temp. Let cool, drain again, then refill with Volvo Penta coolant. Use what was in it, if green stay green, if yellow stay yellow.
Green should be changed every 2 years, Yellow every 5.

The C Model is my personal favorite. Is that a training center?

[@tedsmarinerepair8956]

Yes, it is actually in our Diesel lab here at New England Intitute of Technolgy.
