My 300M is having problems with a loose positive battery cable. The wires from the cable are not staying connected to the terminal connector and one additional cable is too short from the engine to stay connected. What parts can I use to fix this problem. My car continues to have problems starting and surging.

II sounds like the battery lead is connected up incorrectly and it may not be allowing the battery to charge properly or maybe in reverse.
At some point your really need to cut your losses and take your car to an Auto Electrical professional who can visually diagnose the problem - quickly and cheaply.
You will get it fixed properly, and save a lot of heartache !!!!

Bad ground loose connection

try to disconnect the battery for about 20 minutes. hook it back up and make sure you have the positive and negative wires on the right terminal. wrong way can short and burn your entire electrical harness. Check the fuses.

You are describing a classic loose battery connection. If you have the bolt-on battery connectors, make sure that they are CLEAN and TIGHT where they connect to the cable.
I had a vehicle towed into the shop just last week with the exact same symptoms. The customer had all the connections tight. The problem was that he had bought new battery terminals that were painted real "pretty". The Positive was a bright red and the Negative was a jet black. The problem is that he connected the battery cable to the PAINTED part of the pretty connectors....Paint does not conduct electricity very well....

DTC P1705 - NC2 (Direct Clutch Speed Sensor) Revolution Sensor Circuit malfunction or Direct Clutch Speed Sensor Output is 300 RPM or less with Vehicle at 20 MPH or more & with Park/Neutral Position Switch Off

Most probably you have an electrical fault causing the problem and attached is a diagnostic procedure. It could be 2 separate problems and after rectifying the P1705 only would you know it is single or 2. Repair manual shows right on top of transmission, black sensor with single bolt, 2 wire plug. P/N 89413-08020 list price $113.80

NOTE: DTC P1705 is set when PCM receives 2 gear position signals at the same time.

1. Turn ignition on. If any A/T gear position indicator lights remain illuminated when gear selector is moved from that gear, go to next step. If all A/T gear position indicator lights turn off when gear selector is moved from that gear, system is okay at this time.

2. Disconnect A/T gear position switch connector. If all A/T gear position switch indicators go out, replace A/T gear position switch. If all A/T gear position switch indicators do not go out, go to next step.

3. Reconnect A/T gear position switch connector. Shift through all gear positions except Reverse. Using a DVOM, measure voltage between 16-pin PCM harness connector "D", terminal No. 6 (Green/Red wire on 2.3CL or White wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires).

If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Green/Red or White wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Green/Red or White wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

4. Shift through all gear positions except Neutral and Park. Measure voltage between 16-pin PCM harness connector "D", terminal No. 13 (Blue/White wire on Accord or Light Green wire on 2.3CL and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Blue/White or Light Green wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Blue/White or Light Green wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

5. Shift through all gear positions except "D4". Measure voltage between 16-pin PCM harness connector "D", terminal No. 9 (Light Green/Black wire on 2.3CL or Yellow wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Light Green/Black or Yellow wire between 16-pin PCM harness connector "D" and A/T gear position switch. Repair as necessary. If Light Green/Black or Yellow wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

6. Shift through all gear positions except "D3". Measure voltage between 16-pin PCM harness connector "D", terminal No. 8 (Green/Blue wire on 2.3CL or Pink wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Green/Blue or Pink wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Green/Blue or Pink wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

7. Shift through all gear positions except "2". Measure voltage between 16-pin PCM harness connector "D", terminal No. 14 (Green/Yellow wire on 2.3CL or Blue wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, go to next step. If battery voltage is not present, check for a short in Green/Yellow or Blue wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Green/Yellow or Blue wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.

8. Shift through all gear positions except "1". Measure voltage between 16-pin PCM harness connector "D", terminal No. 15 (Light Green/White wire on 2.3CL or Brown wire on Accord and Odyssey) and 25-pin PCM harness connector "B" terminals No. 20 or 22 (Brown/Black wires). If battery voltage is present, check for loose PCM harness connectors. Replace PCM with a known- good unit if necessary. If battery voltage is not present, check for a short in Light Green/White or Brown wire between 16-pin PCM harness connector "D" and A/T gear position indicator, or A/T gear position switch. Repair as necessary. If Light Green/White or Brown wire is okay, check for loose PCM harness connectors. Replace PCM with a known-good unit if necessary.


Hope helps.

Best would be to wet the battery terminals with water, take a sponge and place it on the battery terminals which are corroded and pour water to it, let it stay a while and again pour some water to the sponge, you will note tht the corrosion will start to fade away and thus you will be able to remove the battery terminals kinda easily!.
Hope this helps!

1. Disconnect the negative battery cable.
2. Raise the front of the vehicle and install jackstands beneath the frame. Firmly apply the parking brake and place blocks in back of the rear wheels.

1. Tag and disconnect the wiring at the starter.

WARNING When detaching the hardshell connector at the S-terminal, grasp the plastic shell to pull it off. Do not pull on the wire itself. Ensure to pull the connector straight off to prevent damage to the connector and S-terminal. If any part of the connector is damaged, replace the damaged component.

1. Remove the starter mounting bolts and remove the starter.

To install:

1. Position the starter motor against the engine and install the mounting bolts. Tighten the mounting bolts to 15-19 ft. lbs. (21-27 Nm).

I really hope help you with this (remember rated this help) Good luck.

The ground usually goes through the bracket, as the engine has a ground wire. Do you have the field connector connected? Can you read at voltage on the alternator with the engine running?
