Electrical and starting

Asked by Jnice101 Aug 18, 2019 at 11:44 AM about the 1984 Dodge RAM 150 RWD

Question type: Maintenance & Repair

Hey everyone. First time using this. Not sure it's
this problem has been covered or not. If so please
share link. I have a 1984 d150 318 I've been trying
to get running. I got power and crank. It was firing
with fuel down carb. I took ignition coil off and all
the wiring connected to it to give a good clean. I
reinstalled and now I have no power what so ever
when I turn the key. Not sure if the 2 are related or
just coincidence. I have power from batter and to
starter. I dont seem to have power to ignition
switch but I fear I may not be doing it right. Did I
mess something up when i removed ignition coil?

it sounds like a fusible link go here.... https://www.bing.com/search?q=1984+didge+d150+318+ignition+fusible+link&pc=MOZ2&form=MOZLBR .........https://www.bing.com/videos/search?q=1984+didge+d150+318+ignition+fusible+link&&view=detail&mid=D368B6978248095345F3D368B6978248095345F3&&FORM=VRDGAR.........

Hey guys. I have a new problem. I installed a new starter relay, ignition control module, and ignition switch. I now have no spark. I have 12 volts going to starter relay but only reading 2.3 at ballast resistor and 2.3 going into distributor cap. Would that be something to do with ignition switch? I'm lost here.

The ballast resistor, most commonly found in an automobile ignition system, as a device "inserted into a circuit to compensate for changes, [such] as those arising from temperature fluctuations.. A ballast resistor helps regulate voltage flowing in an electrical system to avoid overloads or battery drainage.As the starter motor begins to crank the engine, it causes a significant drain on the battery. The ballast resistor allows the ignition system to operate at a lower voltage until the engine starts. After ignition, the alternator begins to recharge the battery, restoring the regular voltage. The ballast resistor then functions to regulate the voltage going to the ignition system to avoid additional wear on the system. This is a shot in the dark but have you tested the starter and checked for worn out Bendix bearing or play in the Bendix at all. Also worth a try would be to disconnect the alternator see what you have in voltage to ballast resister and into distributor. Something makes me thing bad starter Bendix or short in the alternator.

Haven't tested any of that. Everything was working fine. would start but die once released key. I'm going to swap old ignition switch in and try. Something happened after I put new stuff in. Would the starter or alternator cauld low voltage? Have 12v into starter relay but only 2.3v into ballast and 2.3 into distributor then nothing out.

Try what you think is best but if it doesn't work then see what happens with the alternator disconnected ( the power wire ) keep it from touching anything as you test and try to crank. If the test is positive and you get 12v to the rest of the system with ignition on but not cranking it over then the problem I would suspect is in the alternator voltage regulator.Have you tested the alternator? If it doesn't test out correctly and wont turn over and the alternator tests good, then I would remove the starter reconnect the alternator and check for power output to the starter as well as check the starter itself.
