IDM Mod Resistors

Anyone have some of these sitting around so I dont have to search online and order it?

I'm sure they are of no use now you've done the mod.

And there will be no used to me to have 3 or 4 of them sitting around like all the other resistors I have that I never use.

Doesn't help that every time i need one I just go buy a pack, even though i already have them. hah.

Not 100% positive, but I can make a pretty good guess. They either combined the two resistors to get the 73.2 kOhm resistance to convert a 120V IDM to a 140V

OR

They combined the resistors to covert a 100V or 110V IDM to a 150V or 160V idm. which some do since the solenoids on the injectors are rated for 160V. But the gain from 140V to 160V is marginal at best.

I havn't pulled my IDM to know which one I need.

The big deal about it is getting 1 watt resistors.

the two resisters in parallel will equal the origanal 64k. its basically an on off switch.my bad 60k.

not necessary. the origanal is only about one eigth watt. the voltage is on the outside of the case near the plug. you can look under the hood and see it

Guys are saying 1/2 to 1 watt resistors on there.

I know its only about 1/8th watt.

the originals are only eigth watt. surface resistors when you see the old resistor, it is about the sise of a popcorn crumb. one half or whole watt dont matter. ive been running 2 resistors inline to get 75k for 3 weeks now, no prob. the watts is yhe amount it can handle, and the rat shack are more than enough.

I thought the problem with radioshack resistors was they are sicone rather than met film resitor and thus not of adequate quality.

I have a 110v IDM and would love to jump on the free resistor bandwagon with William if anyone is willing to part with their extras.

Yeah if anybody has any extras I'd be interested too. Ive been looking for the right ones here locally at the specialyt electronics shops and nobody's had them. Im running an IDM 100.
