Voltage Drop

Full Screen Mode

The electrical cables on most engines are no where near oversized. In fact they are usually on the small side. This results in resistance to current flow and dreaded voltage drop.

There has been reported success in gaining smoother idling, better light beam intensity and improved running performance by increasing the current carrying capacity of the cables:- especially the main negative and positive cables to the battery. That is, the heavy gauge cable from battery +ve to the starter motor, the cable from the +ve of the alternator to the battery and the -ve cable from the chassis to the battery -ve.

On the CB23 G11 there is a quirky cable coming from the rocker cover heading left to the chassis. This is odd because the rocker cover is actually insulated from the block by the rubber oil seal gasket. Relocating the connection to the head itself is recommended. Also a braided strap should be installed, if not already there, between one of the exhaust manifold nuts and the front end of the car.
