Re: 1984 c-4 blues
You can either use a DVOM or a 12 volt test light.
http://www.autopart.com/tools/toolsmain/tool/T_3023.htm A test light is easier to use for this year vehicle. I disconnect the negative cable and install the light between the negative terminal and the ground wire. If the bulb lights you have a drain on the system. Unplug each fuse one at a time until the light goes out. If this don't work unplug the fuel pump relay they can stick. An alternator can also ground out check this. External voltage regulators are a big cause of this type of problem. I think Ford used external in 1984 but I'm not certain about GM but I they used internal voltage regulators at least on pickups. Also check the relay for the computer system. |

Re: 1984 c-4 blues
I mean the ground wire that attaches to the negative terminal. Disconnect this use test light clamp and clip on this wire. Touch the negative terminal with the test light tip. The draw will be between the terminal and ground wire.

Seriously tho', do you have a multimeter? In today's world, you need one. Plug 'n' pray diagnostics is only for stupid rich people. Or stupid people who wanna' stay broke. Put your multimeter on the terminals - NOT the clamps. Got 12V? Let's start there. Post back... |

Re: 1984 c-4 blues
You have a drain on the system is the reason the light stays lite. Unplug the external regulator and check if this stops the drain. Next try the alternator disconnect this and check if the light goes out.

Re: 1984 c-4 blues
Just keep disconnecting items until the test light shuts off. Example as all fuses were pulled. External voltage regulator,alternator,ignition switch, and look for a bare wire going these items. Look for a burned fuseable link by the starter.
Surely you will find it in these areas. The most common areas are external voltage regulator and alternator. |

Re: 1984 c-4 blues
I know what you mean, mine drives me nuts with overheating and then won't run. However, try something simple like is the electric radio antina runing all the time. Mine did that for a while until I figured out to unplug it. Just a thought.
