The cluster is a problem in those and can create a draw.
Here is the procedure to test for draw, including what to expect and when as far as draw.
The first thing to do is a test for a major short. Remove the positive and negativecables from the battery. Put an Ohm-meter across the positive and negativecable. If your reading is close to 0 Ohms then you have a direct short. Youneed to trace the short before you can perform the following tests.
In order to check for parasitic draw, you need to be careful so you don't ruin yourmeter. Here's what you need to do.
get a digital meter capable of reading up to 10 amps DC. Your battery must havea reasonable charge for this test - it won't work if your battery is dead.
If you are talking about the 15amp in the underhood fuse box then it only powers the pcm.
That one on the end of the dash controls the pcm/bcm and the cluster
That is why I specified, Iw anted to make sure we were talking about the same one.
