dmm

Great web page guys. I love cars so I thought I start this as a hobby. My question guys is the DMM. I usually seen guys use a test light to make out wires for remote start installation. The forums and many others mentioned test lights damaging   sensitive equipment. I have a DMM, but two problems only know how to measure ohms. Anyway could someone please tell me how to use the DMM in replacement of a test light. My hypothesis is that the black (Grd) lead hooks up to the chasis of the car and the red lead goes to the wire for readings. Anyway Could somone please help out, really appriciated

Oh and one more thing I have a spdt relay.....its 5vdc,5a@30vdc,69 .40hms.......is this good for changing + trigger to a - trigger or vice a versa.....could someone tell me what to look for in regards to relays.

.

Thanks for the reply KkID. I picked up a relay at a electronic store just looked for SPDT,  I picked up a 5VDC, 5A @ 30VDC,69 40 OHM. What relay in specific should one use when using in the install projects, since its so widely used that was my question? My relay has 5 pins but does not look like the ones in the diagram with 87a 85 86....I have a Normally closed (N/C) Normally Open (n/o) one common and two contacts for the coil.....but the overall setup of the pins is not identical to those in the Schmatics. I have a doubt my relay is not right for the purpose of auto electronics. Could you confirm this. Basically where can I get a Relay from and exactly what is the specifics of the relay u guys use?

One last thing when doing readings in replacement of test lights where should the dial be? For example at ohm or DCV or ACV or DCA. Sorry for the dumb questions but I have minimal experince with DMM.

Guys thanks 4 all the help. I know it may not be a challenging topic I posted but once I start rippin some cars open. I will offically join the party!!!!!

well if you want to test for direct current volts... set it to DCV,  if you want alternating current volts... set it to ACV....

as far as the relay goes, that one sucks.  for anything automotive you should use a bosch 12v, 30amp, 5 terminal SPDT relay.  that way you can use it for something simple like driving a trunk pop or something high current like a 2nd starter or ignition or + trigger doorlocks....

Thanks kkid and sorth140.....I picked up the relay as mentioned @ a local automotive store. As for the DMM, I got the hang of it.. I am practicing on a 94 Buick Century so far so good. Last problem now is getting a Remote starter Brain and all the extras. Best Buy wants u to get it installed by them if u buy the remote starter. Could someone please tell me a place where I can pick one up. I am looking for a clifford or viper or Nordic something that reps. quality. If u guys have something else in mind great!!!! 

Lasty guys I am going to do a 2nd install on a 95 buick lesabre, that already has key less entery and power trunk options from the Factory....can I get the remote starter keyless and the Factory keyless to work together? Do I have to scrafice one for the other or can I keep both?  Oh one more thing whats a trumpit, U can use it instead of a Resistor. I know what a resistor is, just this trumpit I maybe spelling it wrong.

Thanks Guys

Thanks guys 4 the reply..............hmmm wanted to know about TACH........tach is to measured in AC......could any damage occur if it was measured in DC......by accident.

lastly.............Chryslers have multi COIL.............so I only have one Tach on the Remote starter Module. how about do go around this....just hook up only of the coils? Somtimes as well u probably have to go for the Injector pump..(GRND) does that have the same measuring technique as Coil....using DMM..........TACH u measue by setting AC on the DMM and checking to see if the Voltage goes up when u press the GAS........what about the Injuectors on the Chrysler dodge 1996 up Caravans and the Cirrus?

Thanks
