Another stuck starter relay

[bbqfan5909]

Fellas,

I wanted some opinions from yall...My starter relay stuck the other day (first time since I owned it and have started it about 100 times). Would yall recommend replacing the stock relay first or should I do the "doghead starter relay modifcation)? With the modifcation, I read where you will need a diode as well, does it not just work with just the replacement 200amp relay?

Thanks,

Casey

You do not NEED the diode, it is an improvement. It is not required.

diod?? for what? i never saw that

I have replaced mine about 10 times, dont know why. new batteries, good cables and grounded well, now it will not turn over all of a sudden. tested the starter it is good, starter relay justclicks everytime i turn the key. almost ready to just push it off the cliff.

After reading almost all the post on the CUCV section, I have a list of the following I am going to do once my EUC clears and I pick up my truck.

I am going to convert to 100% 12VDC system
12v reduction gear starter
Put in upgraded starter relay
Upgrade the starter solenoid
Manual control of the glow plug system (push button with light) bypassing the controller card.
Replace the fuel filter with a screw on type.
Install brace under steering box.
Install aux transmission cooler.
Cold air intake w/ K&N air filter

I plan on using it in very remote locations for weeks at a time so it being reliable will be very important with me.
I dont want to plan my trip by checking to see how many spare glow plug controller cards I need. Besides, I'm in
south central texas and the glow plugs on my F250 dont run a whole lot as it is...

By correcting or bypassing known problems is just smart in my book...

The mod doghead came up with has worked out well on my 1028. No more problems. as far as the glow plugs go. It should start in round rock without them. Unless it's winter time. The glow plugs are usally reliable. With a good realy and plugs, the card will give you years of good service.

With dogheads mod, do you have the diode installed as well?? What does that do for you? Mine will need to start in cold or hot, its a lease vehicle...

 

[bbqfan5909]

Another question...is there a direct replacement relay that just plugs in and heavier duty?

 

[mistaken1]

I put a 35A SPST switch in the 24V line from the starter relay to the starter solenoid to use as an emergency disconnect if the relay sticks closed. I have tested it while cranking the motor and it does indeed stop the starter motor. I have not measured the actual current flow through the 24V line while the starter is cranking but I would not think it would be that much as it is only a #12 wire.

If the switch is out of sight but still relatively accessible it will act as a theft deterrent device (motor will not turn over without flipping the disconnect switch on).

Buckmaw, by converting your vehicle to a 12 volt only, system, you will eliminate the need for the under-dash relay. (you will need to remove it and add a jumper, or cut off the plug and connect the 2 purple wires)

84cucv1ton, here's Bjorns post on the diode( not need, just one more level of improvement) http://www.steelsoldiers.com/384247-post9.html


bbqfan5909, there is no direct replacement higher capacity relay availible, that is why I chose to replace it with one that was 5 times the capacity.(but needs some adaptation) And no, the diode is not needed(see above comment)

 

[bbqfan5909]

When he refers to kick, I am assuming that means a pop or something like that?

 

[Buckmaw]

The diodes are like 5 for a $1, so its not a huge investment...

You still need glow plugs in Round Rock TX in the winter. Im south of you and I know its not gonna start when its cool without the glows. Mine wont.

 

[bbqfan5909]

I still use my glow plugs...it will still cycle with the new starter relay correct?

Yes this has nothing to do with the glowplug card or relay, If they were working before they should still work.

I was just saying that I wouldnt even try going without the glowplugs being operational even in the summer.
