A quick & dirty way to check for ground problems under load is to use a simple digital volt meter & measure from the ground side of the load to the negative terminal of the battery. If the ground is good, you'll read very near 0 volts. If it's poor, the reading will be somewhere between 0 & supply voltage, depending on how bad the ground is.

Bob and John,
Here's a link to Bob Nuckoll's version of a continuity and load tester . I believe this is what you are looking for.
The PDF document showing it's use and construction are in the link.

John,
Could you elaborate a little more on this gizmo, like maybe a schematic or picture?
Sorry about the difficulty with the wiring.

Howard left me with a very simple, cheap and extremely useful testing setup made with two voltmeters and a D cell battery which allows me to test a circuit under load and identify any weak connections, bad crimps, cold solder joints etc. With this little gizmo I am newly empowered, and have a lot more testing to do.
