still cold start problems


hello fellows am still having problem when cold start only because once is running it will start righ away. i have a dai-rocky 1986 2.8 diesel non turbo and unfortunately the glow plug relay i could'nt find it here in my country because is a old car and there are not other parts for it unless is filters and brake parts but other than that NO no parts for it, so to cut the story short i put in new glow plugs and they heat up just perfect but i cant heat it by turning the kew so my question is can i just connect it directly to the battery and than on the mornings or when cold i'll just pop up the hood and plug it to the battery for a few seconds, is this ok, is it safe? please any advise will be highly apreciated. thanks

Cold start Problems

Hi there,
I have an old Rocky 1985. I have a manual and will be happy to send you the part about the Glow plug relay. Remember there is a Pre heating timer as well. I think you can do it. by the way the relay is made by Toyota and has the part number28610-54080. I know a few scrap yards and might be able to find one for you.
I you send me an E-mail to eval(unescape('%64%6f%63%75%6d%65%6e%74%2e%77%72%69%74%65%28%27%3c%61%20%68%72%65%66%3d%22%6d%61%69%6c%74%6f%3a%70%65%72%5f%61%62%69%6c%64%73%6b%6f%76%40%68%6f%74%6d%61%69%6c%2e%63%6f%6d%22%3e%70%65%72%5f%61%62%69%6c%64%73%6b%6f%76%40%68%6f%74%6d%61%69%6c%2e%63%6f%6d%3c%2f%61%3e%27%29%3b')), I will send you the diagrams.

all you need is a relay to

all you need is a relay to supply the high current to the plugs and a sprung push button switch to control it , so the plugs are only on while your pushing the switch.
the colder it is the longer you need to hold the switch on.
the origional relay basically measures temperature to give a variable time till the light goes out and then clicks in again after the engine is running to allegedly make it run a bit smoother till its warmed itself up.
ive used several old tractors that just had the push button system and they all worked fine.

Why not get a relay ( high

Why not get a relay ( high amp) and wire it in to the heater plugs and run it through to a switch on the dash. Hold it on for a few seconds when cold and good to go . Use a switch with a light to remind you to turn it off though. Did this on and old landrover and worked for years,no problem.


You cannot connect directly to the battery as the standard glow plugs are one of two voltages, these are 7V and 7.5V.

The glow plug relay incorporates a voltage limiting circuit to one of these voltages. The only other option is to find some glow plugs of the right size and fitting which are 12V rated, and replace your originals with these.
