but: I got a few NOS parts and I don't know if they're 6V or 12V. it's headlights, some relays, switches. any way to tell whether they're designed to run on 6V or 12V without frying them? | | | | | Joined: Feb 2004 Posts: 29,885 Kettle Custodian (pot stirrer) | | Kettle Custodian (pot stirrer) Joined: Feb 2004 Posts: 29,885 | Switches don't care what voltage they're used with. The headlights should be marked for voltage, but if they're not, try putting 6 volts to one of them. If it's normal brightness, it's a 6V, if it's very dim, try it on 12 volts. A relay can be checked with an ohmmeter, but you'd need a known good relay to compare with. Generally, a 12V relay will have about twice the coil resistance of a 6V relay.
