Honda Repair: 1994 Accord starter will not engage., starter solenoid, honda accord ex

Question
I have a 1994 Honda Accord EX with the VTEC engine and automatic transmission. The problem I am having is when the ignition switch is turn to the start position, I hear the starter solenoid engage but the starter motor will not turn over. I have replace the battery and the starter and still have the same problem. I suspect that I may have a bad positive cable from the battery to the starter, or possibly a bad or weak ground to the engine block. I intend on jumping the circuits to troubleshoot this possibility, but I would like to know if there is anything else that could cause this problem? In looking at a schematic I find that if I am getting control power to the starter solenoid the only thing left to cause the problem would be a positive connection to the starter or a weak ground. What do you think?

Answer
Good question!! I would definately check all cables running to the battery to make sure they are tight and also check the alternator and if the ground to the block is loose or corroded anywhere you might have to just replace the ground wire check those and let me know if that worked thanks...
