I just bought my first classic car and its a 73 Dart with a 318. It's been sitting for a year and i know it has bad gas but i think the starter or starter relay is bad I put a new battery in it so I know the bat is good just not getting any sound from the starter. This is my first classic car and am new to the carb world, I want to get it running then build it, I'm just use to tuning and efi but now I'm on to bigger and better things. So happy just doubled my amount of cylinders and way more displacement. So all in all any help would be much appreciated.
a few things... the main part of the starting system is here.. do you see the lower right connector labeled ground. that actually goes to the neutral safety switch on the transmission.. the center terminal of 3 when the transmission is in Park or Neutral.. when you turn the KEY.. the power is sent to the lower left terminal called in the image IGNITION terminal.. thats actually the CRANKING terminal. is half the coil winding. the other half is the ground connection..the threaded stud is the wire.. sometimes from the battery.. sometimes from the amp meter.. i forget which way the 73 is wired.. the starter solenoid terminal is the mid sized wire that goes to the small stud on the starter motor.. and that actually energizes the starter motor making the starter spin the motor.. you will also want to.. since the car has been sitting unused for a while. start cleaning the battery cable ends.. use a 3 buck stainless steel wire tooth brush from the hardware or paint store.. clean the other ends of the cables also. .including both large and small ground cable ends away from the battery.. thick one at the engine block. thin at the inner fender.. there should also be a braided ground strap from the back of the engine to the firewall.. usually to the mounting bolt of the ignition module.. did this make any sense..
i threw this together..perhaps it will help..
Yep ill get my DVOM out and do some testing. I'm good with electrical that and alignments are my specialty. Thanks for your help will let you know what i find.
Well I put a new relay in and the starter clicks now but will not spin it at all any ideas?
first .. put a socket on the crank damper center bolt.. its probably 1 1/4" as i recall.. make sure the engine is free to rotate.. make at least 2 complete rotations of the crankshaft.. see the image of the starter motor above.. where the positive battery cable and the brown wire from the solenoid connect.. if you jump those with a screwdriver.. or a remote starter button.. the starter should crank.. since you have a digital volt meter.. print this.. it will help you .. but lets do some static testing.. perform test 2.. while somebody turns the key or you jump the terminals at the starter.. that is negative battery POST To the Engine block.. you should have less than 1.0 volt while attempting to crank the engine.. if you have clip leads. hook to the big stud on the starter motor not the wire to it.. hook your other test lead to the positive battery post.. and attempt to crank the engine.. again.. less than 1.0 volts DC. please DO NOT remove starter motor and attempt to test it on the work bench.. or if you do.. only a fraction of a second .. the gear reduction mopar starters rely on the load of the engine cranking to reduce the max speed the armature will turn.. an UNLOADED TEST for more than a split second can exceed the self destruct speed of the armature windings.. i have found several in the completely fragged condition.. huh. thats strange.. this does not work.. i pulled the cover off the end and it looked like a hand grendade went off inside..
well the starter was bad so i went and got a new one put it on and now it just clicks over and over with no turning or the engine. I hope the motor is not seized. Okay so first got it no power to starter at allthen replaced relay = got starter solenoid to clickthen replaced starter = now it clicks but no engine turnso whats next?
Okay so I turned it by hand it was hard but wasnt stuck but far harder than i thought it should have been so i put some 5w-20 full syn oil in the pass head and cranked it a bit more after about 1/4 it was turning easier but was still hard and did not turn with the starter
do you own a digital volt meter so you can check the percentage of charge on the battery??do you have a set of jumper cables.. ???? lets try something take the pair of ends one red one black.. and hook that pair to the Negative battery post.. take the other pair.. and hook them to the engine block/head.. someplace.. see if the engine cranks now... if it does.. then you need to work on the negative battery cable connections.. look carefully.. this image has both red and black jumper cables ONLY attached to the Negative battery cable and to the engine.. this bypassed the totally disconnected and way too short negative battery cable on this jeep..got pictures??? use photobucket or imgur.. paste links here so i can see..
I have both photobucket and imgur(i love imgur by the way) but yes i have a snap on multi meter. I did the jumper cables thing and i took a vid. Heres the link ( https://www.youtube.com/watch?v=6CNj8FX06YE )
