Charging / fuses

[sadarahu]

Checking around the battery and fuses is easy enough to figure out, but can you tell where the other straps connecting to the chassis are ?
My Battery Charge light is ON again , and no horn. While I was driving few days ago the horn came on for a few minutes, the later it disappeared again. It definitely looks like it is is some connection problem and I'm glad I did not replace alternator yet, as it might be a quick fix. The only problem is to find where the connection is bad. Is there any way I can use multimeter to figure that out.

Grab the wiring diagrams portion of the service manual from the Micro Image Forum (http://www.microimageonline.com/foru...32-YARIS-FILES).

Look at page 60 of the wiring diagrams for the under hood ground locations. With a multimeter, measure the resistance between the negative battery terminal and each of those points. It should measure very close to zero ohms.
