Glowplug pushbutton..

[bbob203]

going to have to rig up a glowplug system since I'm going to maine next week.  asap looking for advice on what kind of button ought I use.

[libbydiesel]

I would recommend using a relay/solenoid in order to limit the current through the momentary switch.  Use a momentary switch rated for the current needed for the relay/solenoid trigger.

Yeah, one of those kinds of buttons that when you push on it  the electricity flows but take your finger off and it stops.  Pushing button turns on relay, relay sends big current draw to Glow plugs, car starts, everyone happy.

[bbob203]

yea I'm gonna get a cheapo starter solenoid for now activate it with the button and figure the rest out later.

[ORCoaster]

Don't forget you need a fuse between Glows and that relay.  Might just use the one on the firewall.  Disconnect OEM wire and replace with Relay feed.
 
Room for Relay near fender behind battery and near Transmission.  Grab a ground from there as well.

this car was a petrol mobile before. I will fuse the connection from battery to solenoid and solenoid to glowplugs. 80amp fuse from battery to solenoid and 60 amp from solenoid to glowplugs. A benz guy diesel guy I know advised marine supply stores sell nice button luckily we have a few since I'm on the ohio river.

Something like this works:

wired to the battery and using the standard glow plug wire as the trigger if you wanted to keep the stock relay setup (if equipped with post ignition secondary glow relay for instance), then into the Vince Walden style fused and separate glowplug wires. Works pretty well.

A start solenoid needs low amperage to operate (large duty relay is all), so it should be fine to just have a hot wire to a capable switch on the dash then to the solenoid.

Thats true, IIRC the standard glow plug wire only delivers the amperage that the relay signal is drawing if using the stock relay setup, not the the amperage it could deliver if connected directly to the glowplugs.

Scored some good stuff at napa today 44 bucks!

Now just have to figure out how to activate the light when I push the button. It looks for ground to come on.

[dieseljunkie69]

Why do you need the light on when you are pushing the button??? That seems like an unnecessary step.

[bbob203]

I don't need it but its one of those touches that a person buying the car might like and see attention to detail.

[dieseljunkie69]

Ahh yes, attention to detail. Wire in a separate light right above that push button?

Yes i could but I want the cluster one to work
