Does "Wait to Start" light come on? Most likely the Glow Plug relay is bad
1988 Chevy 2500 6.2 diesel leaks coolant from rear of block not from any hoses your radiatorIf been told it be coming from where glow plug is also how can you tell if glow plug is working well?
Close to the glow plug is a freeze plug. Go to a auto part store and get radiator dye. Run about a week then with a light look for the color you put in around the plug. This will tell where the water is coming from. If water is coming from the glow plug this may mean a cracked block. Most likely it's a water plug. Some farm tractor part outlets have a tester for glow plugs.
How do tell if glo plugs are good in 1710 ford tractor?
Unscrew and remove the wires from the top of all the glow plugs. Connect a lamp between the battery positive terminal and the glow plug top connection. If the glow plug is good the lamp will light. Alternatively, if you have a meter available, set to the ohms range and connect between the top connector of the glow plug and the engine block. If the plugs are good the resistances of all the plugs should be a very low and approximately the same. A high resistance plug is a dead plug.
What is OBD code P1482?
Cooling Fan output circuit fault On some vehicles it may double for glow plug out put circuit fault Check fan relay in in place Check that fan runs correct, some vehicles the computer can tell if the fan does not start and run correct.
There is a light on your panel that looks like tear drops can you tell you what that means it is a 2000 land rover discovery series ll?
I guess you you are wathing the Glow plug warning lamp.
Where is the relay located at the one that tell your fan to turn on to cool the motor down?

1999 F250 7.3glow plug monitor fault--rt bank only?
Ok before modules controlled EVERYTHING and you can pin-point what cyl has the issue ford uses basically a starter relay to energize the glow plugs. This relay isn't smart it doesn't know what cyl has the bad glow plug so basically you have one or more glow plugs on the right bank that have internally opened and not operating. You can go ahead and pull the right (passenger side) Valve cover and a real easy way to test a glow plug is grab ur test light and put the clip on the positive side of the battery remove the connector to the plug and with the plug still in the head touch the probe end to the tip of the plug. If the light comes on its good if not theirs and open. This is because if the internals of the GP were intact then it would ground to the block and turn the light on if it broken inside theirs no ground and no light. If i was you i'd just do all of them but at least the 4 on that bank. A few years later on some 2002-20011 they came out with a GPCM (Glow plug control module) That ones smart and can tell you what cyl GP is bad. Un fortunately you have to do a few tests to determine which one with that style GP relay.... sorry. Oh ya if you want you can determine which one is bad by removing the valve cover connector and using an dvom set to ohms black probe to ground and touch the red probe to the valve cover connector pins. It's a 9 pin connector and the larger pins are for the glow plugs and they are on each end of the connector. Two on right and two on left. Kinda tricky to not touch the other pins and get a false reading so take your time. So a good glow plug will bench test out at approx 0.5 to 0.8 ohms of resistance. So if you get a 0 reading on pin 8-9 then glow plugs 5-7 are bad if on pins 1-2 then 1-3 glow plugs are bad. Hope this helps now if they all ohm out ok then you have a broken wire between the relay shunt and the 9 pin connector to the RT valve cover. I'd guess a couple plugs are bad. Good luck I do it that way at work all day long and its never failed me. Powerstroke57
Where is the flasher relay located on a 97 tiburon?
if its anything like my 2003 the relay is attached to body control module.dealer will tell you only way to fix is buy new one.900 average price
How do you tell if the radiator fan relay is bad on a 1982 Chevy Celebrity?
Plug a scanner into the ALDL port, then turn the ignition to "ON". The radiator fan should come on. If it does the relay is working. If the fan does not come on it doesn't mean the relay is necessarily bad. That could mean the relay is bad, or the fuse is blown, or the fan itself has failed.
Your horn stopped working fuses all good any idea where the relay is on a 2003 Expedition?
it should be under the hood, there should be a black relay box .maybe long and thin near the the battery .or on one of the fender walls , and the cover should tell you which relay it is,k....
How can you tell if the fuel relay is bad?
Swap the fuel pump relay with another like relay.
How can someone tell if an ac relay fuse is blown?
A relay does not have a fuse. The circuit for the particular relay is fused. You can tell if the fuse is blown by testing it with an ohm meter.
